Problems displaying Gallery page within mambo site

I have just set up my new site and after sorting out various problems, setup the gallery ( which works fine on its own, uploads images, edits etc) and added the additional module to display random images (using the mod_block_random additional module), again this works fine and displays on the page. BUT I cannot seem to work out where I set the filepath or what I need to alter to get the hyperlinks from the photos displayed in the page/ captions to jump to the main gallery page. When I click on the links I get a blank page( with my standard layout and menu)

Any ideas?
Here is the URL to my site: [url]://www.rochdale-archers.co.uk[/url]
