Since I upgraded from 1.5 to 1.6 my lightbox no longer works on custom pages. Obviously somehting to do with my html. When I was using 1.5, this worked well:

<a href="http://www.silkblooms.co.uk/map%20coverage.jpg" rel="lightbox"

<img border="2" src="http://www.silkblooms.co.uk/map%20coverage.jpg" width="300" height="301"></a>

Now I'm just seeing a blank where the image used to be.... What should I change it to now?
