i am having the same difficulty. i have saved it as a jpeg and uploaded it to both websites. photobucket said the file was too large and imgbolt said invalid file. what do i do now?
when uploading a file to imgbolt make sure the extention is in the filename. That could be your problem. That heppened to me when i was renaming my files in imgbolt.
try saving it as another file and then upload it.. it might be a bit larger but if its one of the files youre allowed to use then use that..
