I have this and I would highly recommend it. You can use it to organize your pictures as well as all of your digi scrapbooking stuff.
The thing I like about it from a scrapbooking standpoint is that you can tag items with mulitple key words. For example, if one of your key words is hearts you can click on that and everything tagged with that key word will come up. Also, if you keep your kits together but tag each item in them it is easy to find multiple papers/elements from different kits for one layout.
There is a website where two sisters who digi scrap know EVERYTHING about this program. It has very useful information/tips and there are forums to post questions. I would recommend you check it out too. I don't have the link to it here at work, but I will come back this evening and post it.
I hope this helps.
