We are not able to change Background Images on Cisco IP Phone Model DX650/DX70/80, 8851. We are go through the Admin Guide but Image not display. Kindly share the exact length of Thumbnail and Full Size Image (Width x Height x Bit Depth) with List.xml file format.

Pravin,
I found it at this link. That is the DX?? admin guide. It walks you through the whole process.

8851 devices = 800x480 for wallpaper, and 139x109 for the thumbnail.
Not sure about the DX devices, sorry. Here's a pretty good HOW TO link:

How are you trying to do it actually?
I would guess admin vs list.xml based on what you said.
One catch to doing it via the admin is you wont be able to change it at the phone then.
If doing it via list , make sure to stop and start your TFTP servers.
