Great use of Network Atlas and sorry that you are running into that issue. I'll mark this for a PM to comment on.
How did you get the gif images to have transparent background? When I paste my gifs into network atlas the transparent part turns to black or white. I'm also interested in how to make the network map more accurate like an html image map coordinates. Any update?
We actually copied the gifs into folders in the user's application data folder on the SolarWinds web server....like this:
C:\Documents and Settings\Your_Username\Application Data\SolarWinds\NetworkAtlas\Maps\Orion\localhost\NetObjects\User Graphics\Building\Icon.gif
** I wanted to clarify that the "\Building" sub-folder is not mandatory. We built a sub-folder structure that mirrored our organization based on City, Building, Network Closet, etc....
After you copy the gifs there, close and re-open Network Atlas and you should see them populated.
Also, in order for the gif to have different colors for the various statuses, we created a separate gif for each status:
As far as I know, the popups/hover area issue still exists, and we never came up with a workaround. This project got pushed back/priority lowered and we never finished it.
