Tagamac

Shoebox, an iPhoto competitor that features tag-based organization and browsing through tag recipes, has been updated to 1.7.1. Although there are no release notes, MacUpdate notes that it has improved compatibility with Leopard along with an importer for iMatch and stability enhancements.

Shoebox is definitely an interesting app if you’re looking for something a little more tag-centric than iPhoto, and is available in “Express” and “Pro” flavors at $30 and $80 respectively. If I did much photo management, Shoebox is probably what I’d use (although the pricing scheme is extremely cheap; the only difference is that Express has a limits the number of catalogs and photos you can add, which means you’re paying Kavasoft an extra $50 to essentially toggle off a variable that’s artificially limiting the program).
