@Sarah- thanks! I've considered whether the thumbnail listing is unnecessary, but as plum points out, it's a tough choice. I'll probably end up doing some A/B testing to see what visitors generally use more effectively.
@plum- glad to hear you liked the rest of it. Thanks for giving it a second chance, and getting back to me!
@Juvar & Mike- THANK YOU!! You guys rock. I was not aware of the existence of that CSS property, and it seems like just what I've been looking for. I'll look into it further & report back.
Thanks again to everyone! You feedback is appreciated. If there's more, I'm all ears (eyes?) =)
