Found this web link with a whole load of photo albums of Malta and Gozo. In particular there are lots of albums with photo's of particular hotels and self-catering farm houses (the latter on Gozo).

The photo's are a much higher resolution than found on booking sites and generally give a better over view.

As far as I can see the link isn't selling anything, but as it is in German, and I don't speak the language, can't be sure. Still the site is fairly self explanatory and easy to navigate. I hope some people will find it useful. As usual once in an album click on a photo to make it bigger or click the link in the top right corner to run a slide show.
