User blog:Mippish/Uploading Photo Problem

I'm having a big problem with uploading pictures to the wiki. Every time I try to upload the Cotton Carnival mobile version to the wiki, I always get a "This file did not pass file verification" message. It began to happen yesterday, the same day I uploaded the Dizzy Dessert mobile version, but that one went with no problem at all. I have no idea why it's happening, it popped out of nowhere. I've read the guidelines on uploading a photo too. Why is it causing this to happen?
