canoscan N650U driver installation problem

I have an infrequently used Canoscan scanner which won't work with the new OS X driver that Canon provides because I don't have either Photoshop or Elements, according to Canon support techs. I'm supposed to install the driver into the folder for either of those apps. I don't want either of them—esp. at what they cost!—nor do I really want a new scanner since I use it so rarely. Besides, I just bought a new printer with my new iMac, thinking it was eligible for a rebate, then discovered in the small print (we all know the story) that although Mac listed it as rebate-worthy, it wasn't! So I obviously don't want to buy yet another printer with scanner, etc.

Any suggestions for a substitute for Photoshop or Elements ? Might iPhoto work?

Thanks!
