Compatibility with Adobe Image Ready ver. 7.0

I installed Leopard (10.5.2) and now Adobe Image Ready 7.0 (IR7) no longer launches. When I click on it to launch it the splash screen appears and the last thing it shows is "starting plugins" then the screen disappears but Image Ready is NOT loaded.

I realize that IR7 is rather old. I can't even find it listed on Adobe's support website!

Can anyone tell me if there is a way to get IR7 working again under Leopard? (Worked fine in Tiger 10.4.x.)

If I can't resuscitate IR7 then I need another program that shows you what an jpg or gif will look like at different qualities before saving it. Any suggestions would be appreciated.

Thank you in advance.
