I'm diving into using the HTML popup in ArcGIS 10 and I'm trying to figure out how I can get an image to appear. I have a point file that contains the field "Coll" that has a image name with no extension ("100015"). All the images are stored in a directory ("T:\SEFIS2010_GVdata\SEFIS Video"). I can make an image appear in the popup using this XSL code
<xsl:when test="FieldName[starts-with(., 'Coll')]"> <img src="T:\SEFIS2010_GVdata\SEFIS Video\100015.jpg"/> </xsl:when>
but what is the syntax to append the directory, the FieldName, and the ".jpg" extension?
