which iMac is best??

I am looking into buying a new iMac for my school yearbook staff. which iMac do you think would be best for handling ALOT of pictures, plus also holding Adobe InDesign?? I am trying to get my yearbook advisor to buy us another computer but she is....how do I put this nicely....timid?

Any will be more than capable of handling that software, however not an expert but I belief non of Adobe's products are Universal so you may notice some "slugginess" when using the program, as they run via Rosetta which I belief is a form of emulation.

As BIG D 04 said any iMac will handle without a problem. If you want it to be perfectly smooth, add as much RAM as possible (ie. in the range 1.5 - 2GB) .
