Here's an article about preparing digital images for printing on fabric:

You can do a lot of tweaking to your photos before you print them - the ones that look the most "real" on a quilt actually look way too saturated and "unreal" on your computer screen. If you use the scanned image you see on your computer without applying any tweaking, it can look faded and washed out on the quilt.
The Quilt Show had a show devoted to this a couple of years ago and it was fascinating. Amazon has a downloadable e-book that might help you, too:

I have used a few different brands, and Printable Treasures is good, but Jacquard Print on Cotton is very good, too.
The last time I was shopping for printable cotton, (about a year ago, I think?) I couldn't find any of them that didn't recommend dry cleaning after printing. I wonder if they have a new formulation that doesn't require it, now.
Good luck and have fun with your project. :)
