You can either use a Micro-SD to SD-Adapter and insert the Micro-SD card into it while shooting with your camera, and afterwards put the Micro-SD card into your tablet.

Or connect a SD- or CF- card-reader to your tablet using a "USB-Host Adapter Dongle".

In Photo Mate, check the Storages list on the left. Press the refresh button. You should now see your external sd-card.

You can directly open and edit your images on your sd-card.

Throubleshooting:

• If you don't see the storage in Photo Mate, try to restart your device.
• Some devices (like Nexus) may not support this type of storage access.
