I always download mine to the desktop to post them.
Each system is different, you can google the resize procedure.
If you want to keep the full size image, choose file, save as instead of save, I just add a c at the end of the file name, i.e. "Cool target c" for compressed so I know at a glance which is the downsized file.
Several of my old forums had size restrictions for images. Per image, or total bites per post. Got used to downsizing. It also saves space on your hard drive.
I also regularly delete the clutter from my phone. I have about 25 pics saved on my phone. Miss Tina has over 100.
