Wow! That's a bit on the weird side for sure.
If you change the file name to index.html you get a no recip gallery which would kinda suggest the builder planned on mass submitting the gallery.
Another point of interest is, when going to the domain root you get a "403 Forbidden" error.
Anyway, nice pics and you can use the arrow keys to scroll it but umm, not sure about listing it...maybe if it was done better...
