Small update, I believe I have pissed off everyone in their office. When they answer I hear things like "ugh" and "this fuck" before they hang up on me hahaha
Click choose file, then browse to the file, once it is selected and you see the filename next to the choose file box you can hit the "add new photo" to post it. The upload button doesn't seem to do anything for me either atm.
I wouldn't have found this site if not for a post on reddit. If nobody talks about it elsewhere nobody will find it. Anyway I was mostly just commenting and trying to correct people who were trying to make lemmy and kbin seem really hard to use.
