Photoshop CS2

Ordered Photoshop CS2 this morning. I decided to finally upgrade after seeing CS2 during the workshop I took yesterday. The other reason for the upgrade is that Version 7 does not support RAW image format. A third reason, just discovered, is that looks like Adobe may have upgraded the automatic web photo galleries. I say this because I was just looking at someone's web photo gallery and checked out the source to see that it was done in Photoshop CS2. It looked nicer than the ones available in version 7. Did some price research - $299 educators price was more than the regular $169 upgrade from version 7 price. Now I have Photoshop Elements version 4 and Photoshop CS2 is on the way. I need both because I teach Photoshop Elements and use it often but also like to use the full version of Photoshop.
