I was just fixing to ask if you Activated Profile Fields in the Core Features. Though, this MOD shouldn't have anything to do with that , and should be working as soon as installed. If you have a custom theme, the installer will ask if you want to install the images to other themes. The images must be installed to all themes' images folder for them to appear.
I just went to your site, and appears you are using a custom theme. So you may want to uninstall the MOD, then reintsall, and make sure you click the options to install images to other themes.
