Gmail Labs has a few preview features added to GMail. They are YouTube videos, Picasa images, Flickr images, and Yelp reviews. You can preview all the above in your Gmail before opening up the picture or the video.
I noticed that Flickr, a competing photo service to Picasa lying next to each other. I think it is clever thinking in the part og GMail team. But if you think you have something that GMail should preview, follow the link below to inform GMail crew.
