I'm using Photo Explosion SE. To see even more what this great program can do, check out some of the pictures over on the Edited (fun) picture of the day thread in Theme Parks.
Considering I picked this program up at a yard sale for .50 cents (it actually came with two other programs as well - Print Artist Gold 21 - another awesome program, and a scrap-booking program that never worked) I think I more than got my money's worth.
It really is a good program that is easy to use (although there are a few advanced features that I'm still trying to figure out). If you're looking for a good photo editing program, I highly recommend it.
This is always nostalgic for me as this is the first thing we saw on our first trip to WDW. We had always been to Disneyland all of our lives and in 1996 we were in our early 40's and arrived in Orlando at night. We came in on the "Central Florida Greenway" and after seeing some of the developement we were suddenly surrounded by dark forest and saw our first purple sign. We came to an off ramp to the road I wanted and there was the OKW water tower. Even though I had researched the trip (too much) and new all about the layout it was so exciting to realize how different (and huge) WDW was going to be compared to DL.
