You want the one which looks like a curved arrow to bring up the 'Share' options. Click 'BBCode', select one of the medium sizes, and copy the text below that drop down. You can't do it with some photos (as it depends on what settings the Flickr user has), and if this is the case, it will bring up 'Link' instead. This brings up a really small Flickr URL which is even more forum-friendly than the one I edited yours to be earlier.
Thanks for that. I shall use that over ordinary links in the future.
