My only nit would be that I don't much like the effect when you click "Enlarge" that causes the rest of the page to be a dim background around the selected images. The visual clutter is distracting.
Thank you, Chas. I'm using a WordPress theme. I'm new to that sort of interface, though I believe the theme contains short codes that will allow me to customize the features. I might be able to reduce opacity of background, or even set it to black when photos are enlarged.
The initial layout is very nice, but when viewing an image enlarged, the surrounding images are very distracting. I'd somehow remove the distracting background so all focus goes to the enlarged image. As it stands, the enlarged image competes for attention with the cluttered background. I tried a couple images enlarged and this background distraction caused me to give up on looking at any more. This needs fixing IMO.
