Problem: A color is missing from GIF icon when displayed on a map

Description

A custom GIF icon uploaded to the Points of Interest (POI) Manager Web Service displays properly when previewed but a color is missing when it is displayed on a map created by the Map Image Web Service.

Cause

This occurs when the icon's transparent color (RGB value) is identical to a color used in the icon. The color is displayed as transparent, causing it to disappear.

Solution or Workaround

Change the transparency to a color not used elsewhere in the image. The exact procedure depends on the image editing software. Below are step-by-step descriptions for changing the transparency color for GIF images.
