[Zope] Images and tag tag

[peter]

I use the nifty Image object and an extra tag to it.
like this
<dtml-var "myimage_gif.tag(border=0)">

But what I want to do is this:
<IMG ONMOUSEOVER="this.style.cursor = 'HAND'"
ONMOUSEUP="document.bgColor='#FFCCFF'" SRC="myimage_gif" width=118 height=77
border=0>

I have tried
<dtml-var "myimage_gif.tag(border=0, onmouseover=blablabla">
This is not supported the tag tag. Only border, width, height and alt can be
used.

Solutions? Ideas?
