I've been using Sure Thing Photo and just love it.

First of all I like the price:
free
Secondly I like the way I can organize things, without having to have a gazillion folders on my computer. Basically I can make one main folder, which I have called scrapbooking (how original). Then if I choose to have sub-folders I can, and have done that, but very few - such as papers, ribbons, etc. When I open the program I can then make albums however I want, which I basically made them the same as the folders, although that would be optional. I can right click on the thumbnail and open and actual image in Photoshop, and as far as I know this would work the same if you have a different graphics program.
I can then add keywords and the album I want. When I first open the program, it searches and tells me what is new and I can take just a moment and add anything new.
I won't continue rambling on the virtues of this program, but there are many. The next thing I like is that I can create a totally separate library for photos and categorize them as I please. So I can open the photos library, choose my images, and then just switch to the elements library and pick what I want. As I pick, I can open them in PS, and within just a couple of moments I am ready to scrap.
They do have a paid "Plus" version, but so far the free version has worked just great.
