[Zope] get an image path - not a image HTML tag

[Florian Schuler]

Hello list,

I want to do a form submit with an image.

I do:  <INPUT SRC="<dtml-var OK_Button>" BORDER="0" TYPE="image"
VALUE="Submit" NAME="OK">

But Zope gives me :
<INPUT SRC=" <img src="http://bc-apps:8080/login/images/OK_Button"
alt="OK Knopf"      height="25" width="70"  border="0" />" BORDER="0"
TYPE="image" VALUE="Submit" NAME="OK">

Is it possible to get the path of an image in ZOPE without creating a
HTML image tag ?

Thanks in advance
