Great job with the database du!
I have some more time in my hands this days, so if you want to hand the project off to somebody, here I am
As for suggestions, the one thing that caught my eye since the database was conceived was that the images were hosted elsewhere. I'm not sure of the limits in capacity of your server, but if I were you, I'd try to move at least the top formations to a more permanent location so that we don't lose them overtime.
Also, you could add a "report broken image" button, so that the image can be resubmitted or we can remove the entry accordingly.
