Yes.. it does have another meaning... it means read this image 
*file*...  Wherever you would usually be accessing a file but you want 
to instead access an internal houdini node use op.

Thus this would be the usual usage of the tex() function:

tex("/drive/mytextures/texture.tif", $BBX, $BBZ, r)

There's also a function called pic() which is designed to reference 
cops, so doesn't require the op: syntax but takes the path to the cop. 
Using the op: syntax in tex() essentially makes it work like pic(). Why 
do that? dunno. You get the choice.
