How to add a small image as an Identify Widget result

BarnabyRockwell

Hi Robert,

Here's a strange one for you.  I have an un-attributed, simple RGB raster image in a published service, and I want a small (~150x150 pixel) image showing an explanation to come up in the ID widget results when any pixel in the published raster is clicked on.  Is this possible?

Best regards,

Barnaby

Robert,

I solved the issue by attributing the raster RGB file, which is in ERDAS Imagine format.  I added a field called "Link" and filled it with the url of the legend image (legend.jpg) for every value in the raster (0-255).  This ID widget XML then does the job.
