Forget about resolution. Start to think only in pixel size. Your scrapbook page is 3600 by 3600 pixels. If you photo is larger than that, it will be too large. It will have to be resized. I use the method already suggested - I use the transform tool/bounding box method. It's difficult to worry about resolution and physical size - it's easier just to stick to pixel size.
Didn't "discover" Bon Jovi's music until after 2001 - knew who he was, but followed him more on TV shows he appeared on (Ally McBeal) than as a musical group. Finally got to see him in person and boy, I sure was missing something great. In all, we saw him 3 times in 4 years and each concert was amazing. Good choice, Liz
