Kathy, I can untick it so that it doesn't resample.  I thought resample was a good thing, lol.  I don't, however, see a place for me to select a different resolution in PSPXI.

I also have XaraXtreme which is a vector program and will let you increase a photo and keep the same resolution that you started with.  I'm just not sure if I make the image huge if it wouldn't look grainy anyway when printing.
