[Wtr-general] clicking image (button?)

[Parv]

Hi,
Please Help, as i'm trying to click on on image (button) that fires an onClick() event.

Here's html: 
<input type="image" src="/images/prep/new/submit.jpg" onClick="sub()">

I have tried the following, but none has worked so far:
* $ie.image(:src, 'http://myDomain.com/images/prep/new/submit.jpg').flash()
* $ie.image(:src, /submit/).flash()
* $ie.button(:src => /submit./, :index => 2).click()

Your help is highly appreciated. Thanks!!!
