Images not loading in XML, PLEASE HELP!

Hi, I am trying to use the xml code for the “portfolio” in my site - and i’m pretty sure all the xml is working right, however the images aren’t opening (even locally) when i publish my work. the sample photos DO work though… i checked the jpg settings and i am saving my images as 72 rgb, but for some reason they aren’t loading (locally and when i upload them to the net…but the sample images all work). Anyone have any ideas?
