Because we had more cameras than a BestBuy at our wedding, and many more people in our photos... and most of you are probably on flickr as well as facebook, so this is probably a good way to collect them into one place.
Please upload your biggest possible res. Big pictures are always more fun.
There is also a Facebook group and tons of photos are on there already, and it's great for tagging, but the image resolution kind of sucks.
