Yeah, it's a hack but that's how you have to do it with flickr. As above^^^: Click the download icon arrow, click view all sizes, select the one you want, right click and copy image address.
At that point you can use standard BB code image tags. Paste it into the text and surround it with the IMG tag. Like this:
(img) supercool.com/image.jpg (/img) Replace curvy brackets with the square brackets. (BB code 'code' tag doesn't work on this forum)
