Yep, I never use the <dtml-var... to reference a image object. I alway
use <img ... directly, and never got problem
--------------------------------------------------------------------
That works out great
I threw the dtml-var resu... out and used the <img> and its beutiful now
So if that works why provide the <dtml-var ...> at all??
