I'm trying to answer the Santa question but when I right-click on the photo from the website, nothing happens. I was able to do it from the drill-down before but not from the actual website-part. Thanks!
You can only do it with the small pictures, not on the picture in the item detail. You should be able to right click, and save picture as. Alternatively, you can right click and copy item location, then use the little picture (see above) to add the link to the picture in your post. HTH!
