[mapserver-users] Different image for each point

[Ian Walberg]

Stephen,

This looks perfect, I need to look closer but I had thought the symbols
needed to be defined separately.

Regards

Ian

I have done this by creating a column with the filename in it. You can
then use the column as a symbol name or symbol path or as attribute
column in wfs to OpenLayers that can then be used to point to a
thumbnail directory of fullsize directory of images.


LAYER
   NAME "images"
   TYPE POINT
   DATA "myImagePoints"
   CLASS
     STYLE
       SYMBOL ("/path/to/thumbs/"+'[FILENAME]')
     END
   END
END

Where column FILENAME has something like 'myimage.png' and to do this
you are probably limited to gif, jpg, and png images only. svg will NOT
work.
