That's not his issue, when he re sizes the files using MS Paint, he can't re size the actual image, he can only cut off parts of it as MS paint reduces the frame not the picture. And after 3 years of experience with MS Paint, I still have found no way to re size the image by typing in the desired pixels and letting the program do the work.
McFarland, your best bet is going to be IRFanView, it's free and the download is located on MrMidi's website for AHII TE tools and accessories.
