User blog:Jetgoshi/Why I can't add any character pic in my roster?

For some reason, I tried too add more characters in my roster of my profile. I search it, but nothing happen. Even I put "Megatronidle"(Megatron) or gif. I only put image that I had to force to upload from my computer or I had to take photo from my profile or most recent from Gallery builder. Can any explain?
