I had trouble with this today on my iPad, just email the pic to yourself and tap the on the word "images" in the email and choose a lower resolution. Then save the image that you just emailed yourself and use it in your post.

Don, I use an iPad for most of my posting here's what works for me.

I use an app called SimpleResize.  I found it through the apple App Store it has small ads but that's what makes it free.

I make sure the picture is saved in the Photos because the app lets you choose where you want to take a picture with the camera and resize it or select a photo already taken and resize that one.

There's a slider to select the reduced size (I usually use somewhere around 30%).  Then it prompts you to save it back to Photos.

You end up with two copies of the picture but you can select the second (smaller size) one to directly attach to your post via "Attachments and other options" below the text window.

Personally I'd rather be able to insert my pictures in with my text (like I can with a photo hosting service) and I'd rather not have two copies of a lot of pictures in my library.  BUT... I like the set-it-and-forget-it nature of posting the picture and not worrying about it disappearing in the future as whatever service goes out of business or makes a photobuckt-esque hostage situation.  As long as GTA is here for people looking for help, those pictures will be there to help them.

Hope this helps,
Blue

That's why I use my smartphone to take my pictures then email to myself  I periodically save the pictures to a thumb drive. and also back up my computer files to a 1 terabyte solid state hard drive my brother gave me

I don't use the image hosting sites. That means I have to attach them to posts and the end up at the end instead of mixed with the text, but it works. When I get pictures onto my computer, I resize them using the Microsoft Office Picture Manager as follows (three steps to go with the three pictures):

1. I right click on the picture, which opens a menu, in the middle of which is "open with...". Sliding the mouse over that shows me the list of applications I can open the picture with. I select Microsoft Office Picture Manager.

2. This opens the Picture Manager, where I select the "edit pictures" tab near the top (circled). This pops open a side bar with several useful functions. If I just want to resize, I go for that (also circled).

3. This opens the resize tools. I usually go for a percentage of the original. For my 16 MP camera, which creates files that are about 6.5 MB in size, that ends up being about 20% (shown). The Picture Manager shows what the new size in pixels. To see how big a file that is, you'll have to hit OK and save (CTRL-S) and hover the mouse over the picture. Before you hit save, hovering the mouse over the picture will show its present size, in this case 2.27 MB (this picture had been worked on already).

Paint can work, but it does some stuff in the background, usually reducing my picture size and my picture quality, so I use Paint carefully. The Microsoft Office Picture Manager is good enough for me until I need to mark up a picture.

Thanks for that David. I just learned how to resize with MS Office Pic Manager thanks to you. I've been clicking on the EDIT tab at the top left of the menu bar instead of the Edit Pictures... tab.

I'll be using that instead of paint in the future, unless, as you say, I need to draw on it.

Something I don't understand is the relationship between pixel size and file size.

In looking at earlier posts;

Avator has a pic that is 121.84 kB, 1361x767 pixels.

Later on;

Wayne52 has a pic that is 394.3 kB, 640x480 pixels.

How can there be more kB's yet fewer pixels in Wayne's? Is it due to more detail (info) in Wayne's?

This begs me the question of, how, using MS Office Pic can one judge or show the size in kB's of a resized pic, since that is the parameter that GTA limits us with (650kB/pic)?

Open the pics and you'll see them in their original resolution. The snipping tool just compresses the image smaller. Notice the picture of Rambo and compare the file and resolution sizes with that of the full screen shot that I snipped it from.

Something I don't understand is the relationship between pixel size and file size.

...
You are welcome! I figured instructions with screen shots would be useful. But it turns out this conversation is helping me too...read on (or jump to the end).

As for file size, well, there it can get pretty weird. It comes down to number of pixels and compression.

In picture manager, resizing by changing the number of pixels as discussed above essentially works like area. If I go for 50% image size, I usually get a file size that is 25% of the original. 1/2 the dimensions becomes 1/4 the area. 33% (i.e. 1/3 image size, in pixels) becomes something like 1/9th the original file size in bytes. Usually once I get near about 800 pixels on one side of the picture, it will drop below that 650 MB limit for the GTA.

Now, emailing a picture to yourself results in a smaller file because the email software compresses the file in addition to maybe reducing the number of pixels too. A bitmap picture is a raw data image and is probably the largest file, pixel for pixel, or rather, bit for pixel. The JPEG format introduces varying levels of compression. It reduces the bits and bytes actually used to store the pixelated image. The result is that at too high compression the picture looks grainy (blocks, fat pixels, reduced color range), especially if you zoom in on the image. But compression is only bad when it is overdone. If it weren't for compression a lot of online music and video would be impossible. Even a DVDs use compression to get all the data for a movie on the disk and then to be able to play it back (actually two problems there--storage space and transfer rates). Have you watched YouTube videos at low resolution, especially those ones everybody has pirated from everybody else for the last 10 years? They usually download easily, but between compression and low resolution they look terrible.

You can actually set the compression levels on most cameras. I select the highest pixel counts, but then I tell it I also want superfine quality, i.e. minimal compression.

If Paint saves a file, especially a JPEG, it seems to automatically turn on some additional compression. Other than bitmap, PNG format in Paint seems pretty faithful to the image quality. In fact, Paint tells you: PNG is its high quality export/"save as" option, JPEG is a "good" quality option. Paint gives you no controls, but most software will let you set the level of compression (aka quality or file size). Picture Manager is able to read many formats, PNG included, and can export to other formats. So, here's an example:
    I take a 6.38 MB, 16 MPixel file into Paint and save it as PNG, I get a 13.6 MB file  :o, but still 16 MP. High quality image and huge.
    Taking that PNG file to Picture Manager, I can export to JPEG at differing levels of quality ("export" is below some of the save options under the "file" tab):
         Default JPEG export yields a file at about 950 kB. So, some compression applied.
         Asking for 100% high quality gives a file that is 6.22 MB (almost original size).
         80% quality gives a file that is 1.10 MB. Not quite as much compression as the default.
         60% quality gives a file that is 679 kB. Almost 1/10th the original file size!
         50% quality yields a 580 kB file. Good for the GTA! And still a 16 MP image, 4608x3456 pixels.
         40% quality yields a 498 kB file. 
         30% quality yields a 430 kB file.
         20% quality yields a 368 kB file. Wow, really small (~1/16th the original file size) but still 4608x3456 pixels, and only now do I start to see some graininess or blocks due to excessive compression.
 
So, resizing is good for creating smaller files, but explore that compression setting too! (Or just email it to yourself  ::)) Except that it is harder to use, it gives you a full size picture (pixels) with still very good detail that just resizing looses (see below).

But now the shocker: comparing these exported files, it is pretty hard to tell the differences until I get way down on the quality scale. Furthermore, if I use Picture Manager to just resize the original image to something about 640 kB (27% in my example I just tried it on) I get an image that looks worse than any of them! It is now 1244x933 pixels but looks blurry when compared to even the 20% quality file.

Here's a cropped side-by-side (er, over and under) comparison of a section of my 20% quality picture and the resized version--note the blurriness of the finer details. (This is a very dirty lens...) I'm impressed! I'll have to look into this the next time I'm posting some pictures  :P Thanks guys!

I just open your picture in Photo Viewer and snipped the upper portion using Snipping Tool.
Notice how clear and the file size.

Ok guys/gals and moderators,

I think, I have my photo's posted here, in the media section,
but I can't figure out how to get single photo's posted,
and the photos are in a story board? and not in the correct order,
I do have them number for the correct order.

Need some help how to get them in the correct order and into single photo's for posting etc.

I need some help, a lot of it.

Thank you,
Don

Bill, that is pretty impressive, though I kind of tricked you there. The comparison shot is from screen dumps of close-ups of each file where I made no attempt at file reduction after the screen dump. So it can only compares resolution. The actual clipped files were 35 kB (compressed) and 93 kB (resized).

Nonetheless, that clipping tool is impressive. I've pinned it to my task bar for future use. Here is what I got when I went at the original file, zoomed in on the target area for as near a "full screen" clip as I could get and got the result below. Only slightly larger than yours because the actual screen size was slightly larger when I snipped it.

Looks like for best results, just start with a full screen view and clip away. The screen shot forces a virtual resize (wide and height of your view), and the clipping tool then smacks a pretty heavy but satisfactory compression on it. I'll have to try it on the next post.

Note to others: In windows 10, get on the start menu using the mouse or by CTRL-ESC and go way to the end for "Windows accessories". Since it is such a pain to access that way, right click on it when you get there and "pin" it either to "Start" or "Taskbar" (under "more").

For the sake of reference, let me add the original picture that these are cropped from. The target area is in fact a very small portion. This file is the "20% quality" version.

I'm interested to find out how this works too. I can see that you've added to the album, but the settings must be private somehow--I can't view your pictures like I can some of the others. Also, did you have to resize them to load them to the album?

I am NOT sure what happened to the photo's,
I think I followed the instructions, so I don't know what happened that they don't show up.

I am hoping that a moderator steps in and provides some help for me.

I think that once the photo's are posted in correct order, every thing will be self explanatory,
and I can fill in the blanks or answer any questions etc.

I cropped them down to show intent, then added some text etc.
Then I thought, I loaded them to the media section, but I didn't do some right.

I can't find a way to email them to person, for posting etc.

The ease of adjustment for sizing works very well,
once you have the 3 parts made for the press and pellets you want to resize,
I am finding out that I need to make different base/skirt sizing pins for the different brands of pellets,
as the base dimensions are NOT the same etc.

You can also change the HP pin out for whatever you want, within reason,
I am attempting to make a round domed nosed HP to fit OEM Crosmans pellets,
and then I test for accuracy with my 79 etc.

Tia,
Don

I know I'm beating a dead horse here but I was just curious. I took your original pic and zoomed in on the inside of the scope. Then I snipped a section of it. Again, the file size and clarity is impressive. The first pic is yours
Just click on the  second pic below and maximize your screen.

I use FileBlender. You can batch convert a set of photos to a smaller size. Really easy. For a single pic on your PC you could use paint. Something like 900x600 pixels is OK for a forum.

Yes, thanks Jo! I'll have a look too.

Bill, I won't tempt you with the uncompressed version  ;). That snip tool grabs what it sees pretty faithfully.

Now to see if I can get the media section to work...Don got further than I did. I've found where to create a media album, but I'm not seeing how to put the files in. I'm suspecting I have to finish the preliminaries first and then can add pictures...
