You can also try just to click the link above for testing on the site.
It generates HTML source code like below:
<a href="Page URL" target="_blank" title="Page Title"><img src="Image URL" width="Image Width" height="Image Height" border="0" alt="Image ALT" /></a>The largest image on page is picked up by the bookmarklet.
This works on flickr.
Also works on Picasa Web Album and any other websites.
