Imagemaps always empty

[Stéphane RIFF]

I found why it doesn't work.
When looking in mapimagemap.c i found
that only symbol "0" are process so in the mapfile
you have to set all your symbols to "0" or nothing process

Another question how can i get id of a pointObj so i can query
(shapefile or postgis) to get data from datasource instead of the layer
name ???
