Help calling a function

I need to call a function from a button.

The function is:

Set QFEBridge = CreateObject("QFEBridgeTest. clsQuickBridge ")
Result = QFEBridge.CallQuick()

What it will do is (commented for now):

'Check for errors in running the Quik! Forms Engine
 If objQFE.Results.ErrorFlag Then
 strHtml = "ErrorFlag = 1"
 Else
 'Redirect to the HTML file
 'Dim objFile As QuikFormsEngine.QuikFormOutput
 'For Each objFile In arrFiles
 ' Dim strFileName As String = objFile.FullName
 ' If strFileName = "" Then
 ' strFileName = "ERROR! No forms were generated."
 ' Response.Write(strFileName)
 ' Else
 ' Response.ContentType = "text/html"
 ' Response.Redirect(strFileName)
 ' End If
 'Next

 'Write the HTML file out as a response

The image that should call the function is:

<IMG border=0 alt="Open Form" src="../../../Images/icedit.gif" width=16 height=16>

How can I add code to that image so that it calls the function which should open a page and parse some code.
