I use zenfolio.com and love it, they offer a great trial period so you can see if their services fit your needs. Here is my referral code in the event you do want to purchase, which will give you $5 off the final price: 4RC-5H5-TND.
Thanks for the info. They do look as if they have quite a bit to offer. My only concern with them & other companies I have come across, is that you are able to right click on an image and save it. It defeats the purpose of putting up images to sell! Have you had any issues with this?
