Couple of questions about the browser widget

I haven't managed yet. (can't get it to fire, but hey.. did I mention i'm
no good at javascript?)

Also I noticed, setting the htmltext of the widget seems to run through a
urlencode. (I had a sample page in a field and was setting the htmltext to
it, but it got totally munged.. So I've been creating a temp file and
setting the url which works..)

To show an image you can use something like this..

<img src="file:///C:/Users/Mike/Desktop/dtstuff/billiewow.jpg">

(windows of course) Getting the javascripthandlers to work might take the
input of another. I can't seem to make it go. (Note also, I looked in the
dictionary for the browser widget and used the example code there for the
"set the javascripthandlers..' part.. but the example needs to be fixed.
You need to specify the widget.
set the javascripthandlers of widget "mywidge" to "whatever*
