I think it has something to do with my files. Like (out of example) I went to UKnakedmen, and I saved an image and uploaded it to my server, it comes up fine.

This thing is really frustrating me, I sidestepped around it earlier by using .gif files (which work fine), but I have a larger project with several pages done already on it in jpg that I am working on now.
I have done this many times in the past (create a photoshop doc, slice it and save for web) but never with this issue, and even some of the photos that I have just resized aren't showing up.
