iLife ’04 won’t allow one to install from CD to a machine that has a max rez of 800 x 600, such as an older iBook.

Install iPhoto 4 on an Unsupported Mac may provide information on how to get around this. I’m not familiar with Blogintosh, so I can’t make a contextual judgement about the site’s usual quality of information. I will follow up, though; the site sure looks inviting.

UPDATE: Everything went smoothly, and iPhoto had no difficulty launching and loading a large library of shared photos via Rendezvous.
