Sabrina,
There are a number of alternatives for OS9 (as well as Robbies suggestion), don't underestimate the shareware GraphicConverter. Even with iPhoto 2 and iPhoto 5 at my disposal in OSX, I still use GC.
Even on it's own, it works a treat, but it's completely scriptable (AppleScript) and so with about 30 lines of script I can create my own thumbnails of all my photos automatically. And with about 12 lines of PHP and 30 lines of HTML, I have a single web page that lets me browse the thumbnails of my 14,000 or so photos (thanks Nikon for the D100) sorted by holiday date, etc. and with a single click bring up the selected photo at full size.
Even less effort, which I recommend to everyone, is to visit all the digital camera manufacturer websites looking for free downloads of software for using with their cameras. For OS9 you won't find that much unless you visit the original manufacturers of digital cameras (not the recent naff quality £50 digital cameras). Kodak, Nikon, Canon, maybe even Minolta and others will have OS9 software. Understand that you have to have a camera by these manufacturers to use the software under the license. I, unfortunately, do.
