Dale, if I could just add to your Flickr tutorial, Flickr request that all photographs are referred back to their website, so what I normally do is wrap a link around the photo tags which will link the entire photo back to either the Flickr image or just my Flickr home page.
Example in MR (with curley {} brackets instead of square [] brackets so it will be displayed):
{URL="http://www.flickr.com/photos/28500060@N05/4122453591/"}{IMG}http://farm3.static.flickr.com/2496/4122453591_8a338a6fca.jpg{/IMG}{/URL}
This looks complicated, but is rather easy. Just follow Dale's instructions above for adding the photo, then select all the IMG tags and add a web link.
