Remember everytime you meet a bunch of friends and take pictures. Everyone gets their cameras out the person taking a picture does it from almost as many cameras/smartphones as there are people. Or the person with the best camera takes all the pictures and promises to share. Well, 9/10 times I never shared any pics back with my friends.
I have an intuitive mobile app idea for photosharing with a lot of ease. Now that I got you interested, send me a message if you know how to develop an app for Android or iPhone.
