I posted this before, in case anyone still cares. But there is a work around for tapatalk. If your posting pics via tapatalk, if you want them to show up properly you have to, after you uploaded your post and pics via tapatalk, go to the thread via your browser (not via tapatalk) and just hit the edit button, and then hit save. Your pics will then show up on all platforms.
Or you can do what others have said and just use photobucket or something.
Just an FYI
