Probably just the images html code being set the the wrong path. Try posting some code in relation to the image(s) that won't load and the locations of the images then it will be a lot easier to provide some additional answers to how the code should be. And also are these images database driven or stored in a file system?
Well as I said, when browsing the php file in the web browser, if you go to view->source, does it show in the source the proper locations of the pictures? Try to copy and past those locations into the url bar appropriatley. That is the most likley problem that the address to each picture is incorrect due to something like a moved folder.
Ryan it would be a problem of image path .....you can check the image path by directly access the image from the browser which ever you are using like this http://localhost/image_path_name/image_name.jpg (fill correct image path and image name)
