Can't post

Hi,

Tried to post a thread in the Film and Processing section and I wanted to attach a couple of photo uploads. The site wouldn't let me upload photo number 2, it said "There was a problem uploading your file.". I adjusted the file size so that it was actually smaller than the photo that the site did accept, but to no avail.

I therefore uploaded the picture to an external photo host and included a link to it, then I got this error message instead:

"Your content can not be submitted. This is likely because your content is spam-like or contains inappropriate elements. Please change your content or try again later. If you still have problems, please contact an administrator."

What is wrong? And how do I contact an admin?
