Forms :: Passing Parameters From Winform To Html Document?

i have a windows form that has a web browser control.

i need to pass the value from the windows form to the html doc.

here is my problem.... can pass the value across to to a function in the html page but when i try to pass the same value to an image tag in the same document it does not read the value.

here is my code from the winform
If e.Url.Equals(wb1.Url) Then
wb1.Document.InvokeScript("fetchImage", New Object() {path})
End If

it passes through the variable 'path' to a function in the html doc.

heres the code for the html doc.... this part of the code works

function fetchImage(path) {
var now = new Date();
var zm_image = new Image();

[Code]....
