OK- help this poor Luddite.

I'm trying to upload some photos on this site, and am having no joy. I click on the Image tab, select Add Image, and am told I need to log in. So I do. Once I'm in the matrix, I repeat clicking the Image tab, and get a blank screen. Anyone else have this issue? Or better yet, anyone have a solution. I'm using Google Chrome as my platform. Cheers, El
