If you're an iPhone user who takes many, many photos, only to have them sit unused and unseen on your phone, now you can make some money off of them with the Foap app.
Foap is an application from a Sweden-based company that lets you sell your untampered-with photos (so you can't use Instagram or other filters to augment them before uploading) for $10 a pop. However, you only get $5 from that since Foap gets 50 percent of the sale. Nonetheless, using Foap, you might be able to sell the same image many times over, which means it is very possible that you could generate a substantial amount of cash.
The Foap app is definitely a useful tool that North Americans are sure to pick up quickly. It only launched a month ago and it already has over 10,000 downloads. Plus, if you're more interested in buying photos then taking them, Foap offers buyers a system of credits so that you can buy in bulk. There is also a "mission" concept, in which buyers can ask members of the Foap community to submit photos that fit a specified theme or idea.
