We have a new map service based on a services of old paper maps that have been scanned. Since it's a raster there is no way to display a legend. Is there a way to embed a hyperlink in the map service's item description section? I tried using embedding the http address in html href tag but that didn't work when viewing the properties in ArcMap.

What other approachs are there for displaying a legend for map services of raster data for use in ArcMap?
