Your Cats photos

I'm sorry I'm sure there is an answer to this question already but I've tried searching 3 times and my browser & TCS server just aren't getting along.

I'm trying to upload pictures of my cats to my cat sites, but the server won't let me.

Am I uploading pictures that are too big (what are the specifications?)
or am I not allowed to yet? (and what are the restrictions)

Thank you!!

Are you talking about the Cat Pages? If so, that was addressed in this thread, Problem with Cat Pages???.

Or are you talking about pictures in posts?
