We don't allow embedding so we can keep a clean and tidy forum. As for linking to flickr, it's easy:
URL of an image within a gallery:
http://www.flickr.com/photos/rothliu/4269005917/sizes/l/
Direct to the image:
http://farm5.static.flickr.com/4025/4269005917_d56abf8f14_b.jpg
Right. For a second I forgot Flickr can do more than images, but either way, embedding is not an option here
