"As long as you can email them to us" - is this the only mechanism for sending the photos? I realise you might have written this to simplify the page, but my first reaction was that I'd rather be able to upload them. Then on the 'Photo Guide' I do read that I can upload them. Perhaps instead of that sentence on the home page it would be better to link to the Photo Guide.

Looks like a pretty good idea though :) Good luck with it!
