Gmail live image previews

When composing a Gmail message in a separate window, you can drag images from most sites into the body to attach them to the message and see previews displayed in-line. On the Mac this works in Safari and I believe Firefox as well. Would any readers care to comment on this functionality in Windows?

This is different from Gmail Labs features, such as “previews in mail” for sites like Picasa and Flickr, because those features focus on displaying previews for messages you receive. While I used Flickr for my example, an image from Apple.com worked as well.
