Mike, Adobe makes a "streamlined" version of Photoshop they call Elements that only runs about $99 that should allow you to do what you want. It's like a watered down version. What you have to understand is this, you say "put a different background in", it all sounds realatively easy when we say it, but in practice, you need a piece of software that is going to allow you to "grab" or select the background properly in order for you to be able to change it in the first place. It's not terribly hard to do, you just need a software that has the flexibility to do a thing like this. That's why Photoshop has that type of price tag. There's probably 5 or 6 ways you could go about "knocking-out" backgrounds with it! The cheaper you go, the more rudimentary the proceedure you have to work with and the less controll you have. I've been using Photoshop for years, and quite frankly, I couldn't live without it! I like the control and the variation I get with it. I've also use Elements a bit, and while useful, it's no photoshop. You might look for a used copy of Photoshop on eBay. You might be able to score a version that is once or twice removed from the latest and you just might find yourself a bargain. Make sure it's not a copy! Good luck!
