The photography on them isn't half bad with a resolution of about 300 by 200, they can store between 20 and 240 photos (depending on the one you find), and it turns out the little guys were just made to be hacked. It's those chintzy little keychain cameras that they sell for $10-15 a pop. Turns out there is at least one - and they sell it at your local drug store (CVS/Rite-Aid/Walgreens/etc.) Why isn't there a normal, cheap, run of the mill digital camera that's controllable by Arduino? And current techniques for stand-alone Arduino photography typically try to capture raw image data from CMOS cameras popped off of cell phones.and believe me, unless you need to digitally upload or alter those photos in real time, you don't want to go down that road.
Webcams aren't practical for applications like kite photography or public photography, unless you feel like buying a 200 foot USB cable.
Photography options for the Arduino are few and far between.
