A digital picture viewer keychain is a great way to display photos for friends, families and clients. A digital frame can hold different numbers of photos, depending on the memory size. Picture keychains work like external hard drives. They hold a specific amount of data and display it on the screen. Two different formats are available: FAT32 and NTFS. Most of these devices come formatted with FAT32, which won't hold images over 4 GB. There is a simple way to reformat the device to NTFS, which stores files of all sizes.
Preparing the Device
Attach the digital picture viewer keychain to the computer via the USB port.
