I'm confused. If I plug <dtml-var size> anywhere else in the above script 
it prints *1*. In other words, I have a dtml method called *size* and the 
only thing in it is the number 1. If I replace *size* with the number 1 in 
the above <img> tag, width yields 1008 as it should (1008*1). So I don't 
understand why the <dtml-var size> doesn't work when called as *size* in 
the External Method. What am I missing?
