Hi, I don't know exactly what your problem is, but check these things:
1. Make sure you replaced the correct images. XP Home has 1, 7, 9, 11, but Pro doesn't have the same ones.
2. Did you download the file, and import into paint shop pro?
3. Are your pics the right size?
Oh, and before I go, do yourself a big favor, and make a copy of the XP line in boot.ini, with it's original [old] text. Just put it below the one you changed (the one that says \kernal=, etc)
Doing the above will make sure that you can still boot into XP, even if your boot screen messes up, or whatever. I made the mistake of not making the backup, and my friend said I should change the partition number [DONT DO THIS UNLESS YOU KNOW WHAT UR DOING!] to some other number, to get it to work on my other drive, and well, lets just say I had to reinstall xp after i restarted.......and on top of that, my friend was borrowing my disk... so i had to go to crappy windows 98... arrghh i hate win98!
Once you have your boot screen working 100%, then you can remove the backup line. But.....BE WARNED!
