Use Migratr to Transfer Photos Between On-line Sharing Services

"Freeware application Migratr moves your digital photos from one photo sharing service to another, metadata and all. We're pretty into Flickr here at Lifehacker HQ, but Flickr's free account only serves up 100MB of storage space, so we can understand if, for example, you want to move to the 1GB pastures of an integrated Google service like Picasa Web Albums. But since no one wants to lose all the metadata they've plugged into another site, Migratr preserves all of this when you migrate your pics. Migratr supports importing and exporting to and from Flickr, 23HQ, Zoomr, SmugMug, and Picasa; it preserves each photo's title, description, tags, and albums. Migratr is freeware, Windows only."
