Here's the issue:
Code:
http://www.gfx-core/pets/picuploads/gif/1f298def9c8c7428e40e2d5bae62ff8c.gif
It looks like your domain name is entered wrong into inc > config.php. You should have gfx-core.com for the domain, where by the source code for your images it appears to just be as gfx-core and is missing the .com part.
Please download your inc > config.php file using a FTP program, open it in wordpad and make sure all of the details are correct. :)
