My friend Steve commented on this post, where I mentioned that I am trying flickr as a photo management site, mentioning SmugMug. SmugMug is a pretty nice site to to photo management. They offer a 14 day free trial, and then several different subscription options. Similar to flickr, SmugMug has several desktop uploading clients available. In addition to that, there are some site that will let you automatically migrate from flickr, or other sites.
I really like the look of the site, as the albums look more polished than the albums do on flickr. Also, since the main focus of SmugMug is not sharing, it leave the UI to be uncluttered.
I uploaded about 300 photos and added tags for each of them. The upload process was pretty painless, and adding tags to each photo was a lot easier than it is on flickr. But unfortutately, the site was getting pretty unresponsive, when I was attempting to look at my uploaded photos. In fact, many of the web browser connections were timing out, so I had to manually try the connection again.
The other problem is that it doesn't appear that you can have a single photo in two albums. You can duplicate the photo, but that is not exactlywhat I want to do.
