Okay, this problem has been going on for a while now, but I only just now thought to address it. Basically, I can't post images into threads while on a desktop. I know it's not my personal computer, because the same thing happens when I use the school computers. I use the format, but it says something to the nature of 'that format is not usable on this community' Now for the most part, I can post ages while on my phone, but that's it. Every time I use a desktop I get the same message.
