up until now I have gone with the same solution as u suggest, zax. but now users of my webpage are complaining :p they find it too difficult to navigate through the gallery by using the captions as links to subgalleries.
so does anyone know how to (if possible) make an image into a link, f.ex to a subgallery?

I also have a joomla-site, and included the simpleviewer within a wrapper, easy peasy :)
