URL—URI that specifies where the phone obtains the full size image.

The following example shows a List.xml file that defines two images. The
required Image and URL attributes must be included for each image. The TFTP
URI that is shown in the example is the only supported method for linking to full
size and thumbnail images. HTTP URL support is not provided.
List.xml Example
<CiscoIPPhoneImageList>
- <!--
Please Add Images to the end of the list
-->
<ImageItem Image="TFTP:Desktops/95x34x1/TN-Mountain.png"
URL="TFTP:Desktops/95x34x1/Mountain.png" />
<ImageItem Image="TFTP:Desktops/95x34x1/TN-Ocean.png"
URL="TFTP:Desktops/95x34x1/Ocean.png" />
</CiscoIPPhoneImageList>
The Cisco Unified IP Phone firmware includes a default background image. This
image is not defined in the List.xml file. The default image is always the first
image that appears in the Background Images menu on the phone.
Each background image requires two PNG files:
Full size image—Version that appears on the on the phone.
•
Thumbnail image—Version that appears on the Background Images screen
•
from which users can select an image. Must be 25% of the size of the full size
image.
Many graphics programs provide a feature that will resize a graphic. An easy way
to create a thumbnail image is to first create and save the full size image, then use
the sizing feature in the graphics program to create a version of that image that is
25% of the original size. Save the thumbnail version using a different name.
