I like it but I'd like to see images right in your page instead of going to an external website which sometimes is not even dedicated to stained glass making hunting for visual gratification really painful.

So, I'd add more visuals to the main page just like on your 'search' link, move the map to the bottom, let visitors know of every new location to keep them engaged and coming back for more, make a gallery sorted by most liked, viewed, commented, valuable (subjective based on history, cost, location, etc)
