OS 10.5 Leopard & Photoshop 7

I'm pretty sure that Leopard only supports CS3 (Ps 10.x) so you'll have to purchase a copy of that. I can't find the source where I read that, so I apologize for the lack of evidence and more information.

Welcome to Apple Discussions!

Here is Adobe's Leopard Compatibility PDF:

Basically it says that Photoshop CS 2 and earlier "likely to encounter issues for which there is no resolution". So yes, CS 3 is a prerequisite for Tiger. Since you have a PowerMac G5, you can install a second hard drive inside of it with Tiger or earlier installed to run CS2 or earlier.
