Windows XP can do different formats, but the larger it (the picture/graphic) is, the faster and more powerful the machine has to be to redraw the screen fast enough. Thus it takes more CPU cycles to try and "keep up". To test, take one of the problem pics and use a graphics program to look at it's DPI and if more than 72 DPI, resample it down to that, save it as a different file name and see what happens. On my older machines, I have a black screen (no background, but you can use any solid color you want, it just takes a little extra resources) just for this reason.. Leaves more of the system speed and a few extra resources so that it doesn't have to be wasted on showing me a picture.. ;-) It's possible you have other issues, but without being able to look at the machine, it would be hard to guess.. Try a solid color background and if it's OK, I think you have the answer.
