ZAP performs automatic detection of the USB port, thus when you plug in a digital camera it beeps the speaker and ask you if you want to access it. Use the "graphic" displays mode if you want to see the thumbnails of the pictures stored on the camera.

Advice: do not work on the folder matching a digital camera, instead select the pictures you want to keep, then use "copy" to paste them on your hard disk, where you will be able to do what ever you want with them.
