howdy folks! i've sucessfully loades pictures on to the RadioShack Gigaware 16-1033 Digital Photo Keychain, but once i unplug the usb cord from my computer there doesn't seem a way to turn the keychain on... it only shows the pictures when it's plugged in. it's not a charge issue 'cause i let i charge for 24 hours, thinking that might be the problem... any suggestions! thanks a lot!
