USB Photo Backup

Develop a software that will work with our USB hardware that easily lets you backup all the pictures in your computer into the USB stick in one easy step. Once a user inserts the usb stick into any computer, a pop up will come up that says "start backup" and it will automatically find and copy all the jpg, gif, png, files to the usb stick once you click start. The user will not be required to download any software to make it work, it should be instantaneous. Also, the Photo USB stick will have the ability to recognize newer files and only copy the newest images when you use it again to save your recently added or changed pictures. Please include sample works you have done in this bid.
