cs5 is better
PS 7 is one of the older versions of Photoshop, before Adobe's merger with Macromedia. Photoshop CS4 is the current version of Photoshop (soon to be replaced with CS5 this summer). While the two have the same developer and history, CS4 is a much more advanced version of the program. Tasks that required separate programs or plugins (mini-programs that you can buy that run within PS) with PS 7 are now standard in CS4.

You can use Photoshop CS3, CS4 and CS5 with Mac OS X 10.7 (Lion). Adobe reports that Droplets will not work but they are working on a fix for that.
The extended versions have all of the features the normal ones do but they offer extra features such as the ability to import and edit 3D graphics, video enhancement and more tools to use for editing images etc.
