so you find a website that allows you to copy and paste and save i use uploadfiles.io then once you finish a picture you would like to save press the save to computer go to uploadfiles.io and drop the file there copy it then paste it wherever.

I use Ufile, so I'll use that as an example. If someone gives you a Ufile link, go to it. If you don't have an account, wait 5-10 seconds and press the free download button. After a few seconds, it should be in your files. Go to FA and press the upload file button (Settings-> grid with green arrow pointing up). Pick the newly downloaded file. You'll see a disclaimer saying that the anim will clear, so pick yes.
