Tip 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.
The PNG files for background images must meet the following requirements for
proper display on the Cisco IP Phone:
• Full size image—320 pixels (width) X 196 pixels (height).
• Thumbnail image—80 pixels (width) X 49 pixels (height).
Tip If you are using a graphics program that supports a posterize feature for
grayscale, set the number of tonal levels per channel to 16, and the image
will posterize to 16 shades of grayscale.
Configuring a Background Image
To create custom background images for the Cisco IP Phone, follow these steps:
Procedure
Step 1 Create two PNG files for each image (a full size version and a thumbnail version).
Ensure the PNG files comply with the format guidelines that are listed in the
“PNG File Requirements for Custom Background Images” section on page 6-5.
Step 2 Place the new PNG files that you created in the following folder on the TFTP
server for each Cisco CallManager in the cluster:
C:\Program Files\Cisco\TFTPPath\Desktops\320x196x4
Note Cisco recommends that you also store backup copies of custom image
files in another location. You can use these backup copies if the
customized files are overwritten when you upgrade Cisco CallManager.
