Digital Image Pro, a newer version of Picture It that has been renamed, is a great beginner to intermediate program. It is easy to navigate and learn, can do a ton of creative effects and it accepts plug-ins to expand its capabilities. I've been digitally scrapping for more than 2 years and I still love it. Unlike earlier versions of Picture It! it works very similarly to other image editors, so it is easy to take what you have learned and apply it other programs.
In case you are wondering, plug-ins are like "miniature programs" that can "plug in" to your software and include a lot of creative effects. There are lots of freebies out there as well as some commercial plug-ins. Some you may have heard of are Eye Candy, Virtual Photographer, Almathera, etc. This is a pretty inexpensive program, though it doesn't have a trial that I know of. I highly recommend it.
Here is my gallery. Most of the LOs were done in Digital Image Pro. The first 7 were done with PSE 2, also a great program that I'm still learning.
