Hi
I have the need to display different images for different features in my layer.
Dynamic symbolizers seems like a perfect solution. So I had to create a style
sheet which looks like the one below. ${image_name} is the column in the table
which contains the image to be displayed. This works perfectly for the png
image that is produced. Each feature gets its own image. However, this errors
out in the KML. The error in the kml is shown below..... Any clues what I
should be doing here.
Thanks
Ashok
