Can I make a suggestion for this to make it even more awesome but not get in trouble over copyrights. Let people take a picture of the front and back of CARDS THEY OWN!!! and link them to the listings in the crew list.
Simple database entry... just need a save directory, use camera, and a modelID, frontpic, rearpic the first one is the ID you use in the list already, the last two are just filenames.. simple table...
DO NOT PROVIDE CARDS but let people use their own!
Just a thought.
Although Wyrd Putting out an app that does this would be amazing.... just sayin
