I'd love for someone to make photo-sharing not suck horribly. Yes, Flickr is pretty great for some scenarios, but I still have yet to find a great solution for the following scenario:

1. I go to say, a wedding (but it could be anything) with a group of friends 2. Many people take pictures 3. After I come home, I want to easily look at, and optionally download, high quality version of all my friends photos for this event.

Right now, I see people using either Facebook, Kodak, Flickr, etc (I can't easily download high-quality collections), emailing several zips, or if they have a server, placing the photos on their and providing a link. There has got to be a easier way and I'm dying for someone to build it.

For the record, I don't think ideas are worthless. I'm just not going to build this anytime soon and I'd rather an awesome solution sooner rather than later.
