thanks for all the advice. i looked at the sites recommended by everyone, but they are too expensive and complicated for what i'm looking for at the moment.
the main problem is that the other ones are more about you making money off the prints - which is great if you're selling your art pictures to the general public. however, i'm not looking to make money off these prints, only distribute them to the family and whomever they would like to share them with. this is partly because they already paid for my services, and i'm not trying to charge them a second time to get the images printed. in the future, this might change.
i'm now seriously considering just using picasa. i can pay 2.49 a month for 25 gigs of space, and i really only need it for a few months because it will be for two weddings. this way, i can upload full quality jpegs, share them, and they can choose to do what they would like with them. also, picasa is very easy to use for most people because they are already familiar with it.
they offer the following companies to make prints from:
LifePics Network of Local Photofinishers
Also, people can just download them and choose to get them printed wherever they like.
Does this sound like a terrible idea? to me it just makes sense because it is cheap, easy, and allows the customers to do what they like with the images that they already paid for.
like i said, in the future i will probably do something a little more "professional," but this seems like a good option for the time being.
