Ok while they aren't CDs in a package, they aren't subscription based either... I ran into it last month or so, its a list of about 70 or so sites offering free stock photography. Pretty interesting, gave me alot of photoshop fodder to play with.. Anyways heres the list... http://pstutorialsblog.com/?p=44
I also recommend istockphoto. I love it, although they are raising there prices at the end of this month.
As for the person who suggested google. Those images are not royalty free!!! You can just pull anyimage from the internet and use it!!!!!!
Hmm, aren't you allowed to use those images (from google) if the images are just for non-comercial / personal use? Good point though, I didn't think about that.
Oh, also, I sometimes use stock photos from here; http://stockart.deviantart.com/
but generally I find the methods of browsing cumbersome - especially since you can only look (the long way) through various categories if you don't want to fork out money.
If you give them shiney round pieces of metal, they'll let you search, but I like my shiney round pieces of metal too much
