After this excursion, I had some more adventure. After much research, I'd determined that Adobe Acrobat and Photoshop are indeed compatible with Windows 7. I sure didn't want to make this big investment, only to be told they weren't.

So today was the big day. I've got the two programs installed on the new computer, so I'm in business. The 'CS4' program isn't that much different from the CS2 version, so I'm not completely lost. But there are some new things. The 'save for web' feature is really effective. Here are two versions of a photo taken last year at the Nineteenth Annual Colorado River Balloon Crossing:

The first version is a png using only four colors and 'diffusion', and is still very recognizible. It is only 23 K! The second is the 'save for web' jpg version of it, saved at '63' quality. It is only 41K!
