Defining the local image cache and local image cache URLs
You must specify where images are stored by using one or both of the IMAGE_CACHE_URL or LOCAL_IMAGE_CACHE_URL keys.
IMAGE_CACHE_URL
The IMAGE_CACHE_URL key defines the URL that is used by the browser to retrieve images. It can be either a full URL or a relative URL, and it can be an externally accessible URL.
Example of a full URL
<appSettings>
<add key="IMAGE_CACHE_URL" value="http://www.myserver.com/SPSSMR/ImageCache/ImageCache.aspx"/>
</appSettings>
Example of a relative URL
<appSettings>
<add key=" IMAGE_CACHE_URL " value="../ImageCache/ImageCache.aspx" />
</appSettings>
If IMAGE_CACHE_URL is not set, it defaults to the LOCAL_IMAGE_CACHE_URL.
LOCAL_IMAGE_CACHE_URL
The LOCAL_IMAGE_CACHE_URL key defines the location of a local image cache that the CATI player can use for retrieving templates. The URL must be relative to the Accessories server.
<appSettings>
  <add key="LOCAL_IMAGE_CACHE_URL" value="http://GREEN/SPSSMR/ImageCache/ImageCache.aspx" />
</appSettings>
If LOCAL_IMAGE_CACHE_URL is not set, it defaults to the IMAGE_CACHE_URL.
