I found them at Michael's (the craft store). I have also gone to Wolf camera and used their machine to resize. You put the pic in, up comes the pic on the screen. You can resize or crop almost any way you can imagine. I did this for a scrapbook, and for a picture that I wanted to fit a frame I had already that wasn't large enough. The other option is to go to Michael's or a frame shop, and have them cut an mat for your picture that would fit an 8X10 frame. I've done this too, it cost under $10.00.
