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.
