You'll get weirdos and picture collectors wherever you post it.
I've had good luck selling things on craigslist, here, and on RJ. No matter what, you'll have people wanting to give you $200, 3 goats, and a bushel of butterbeans for it.

I've always just attached pics directly to the post here on moparts. Never used a hosting site.
