HD Photo Not Sending:

Currently, HD image request is only supported on Gen 1 Reveals with the firmware ending in B506, Reveal X, XB, and SK models. 

There are several reasons an HD image will not send to your app from the Reveal X  including

• signal failure at the time of send
• low battery
• too slow of an SD card (requirements: Sandisk or Lexar, full size (not microSD w/ adapter) Class 10, U3, 16-32GB)
• picture has been deleted from the SD card.

Another reason the HD Image may not send is if your payment method failed or is not up to date.

Only HD images that are successfully sent will count against the 50 pictures that you paid for.
