PNG File Specifications for Custom IP Phone Background Images
Each phone background image requires two PNG files:
• Full size image—Version that appears 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.
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.

• Thumbnail image—80 pixels (width) X 53 pixels (height).
• Color palette—Includes up to 16-bit color (65535 colors). You can use more than
16-bit color, but the phone will reduce the color palette to 16-bit before
displaying the image. For best results, reduce the color palette of an image to
16-bit when you create a PNG file.
