I am having trouble adding attachments. I have tried everything, reducing file size, changing file size and name, removing spaces. Any clues how to get image files uploaded? this is the error I get on a 25 kb file (reducing to 18 kb did not help)

This is not a valid image file.

I tried to make an Album, as per FAQ entry, but found no Album link in my user control panel.
