Hey ... Anybody got advice for about how to protect images for a site that's primarily image-based?

I've considered many options and I'm totally confused at this point :err:

The first thing to really consider is whether I should allow the content to be downloaded (and then use watermarks, etc.) or if I should somehow prevent the downloading of images.

Am I confused for nothing (ie: will ripping-off of images be so minor that I shouldn't even take certain measures)?

I'd like to allow downloads just because I think members would get pissed off if they couldn't. I know I would.

Any suggestions would be awesome. Maybe even if you could let me know what you're doing on your sites.

Thanks guys :-)
