Well, there isn't much to share, I don't think (not in that regard); you just comment out the call to catrow() and then modify the call to display_gallery to suit your needs. Turn off everything else.
One thing you can do is use the $childnav variable which works as usual, just not the drop down variety, but does give you the location with breadcrumbs.
I'm not saying the site was a snap to put together; obviously there is alot of code I had to write, but the index page itself is just the categories removed and replaced with the dropdown code and the call to display_gallery to provide a much later Recent Photos box.
Please do not PM me for support or sales questions. Thank you for your understanding.
