Find element in webbrowser based on src

Hey, so again i have one of my many webbrowser control questions. This time the question is, if i have a webpage source code that looks like such:

<img src="<img url>" width="62" height="20" alt="LIKE">

and i want to invoke the element based on the image url, how can i do this?
I tried:

For Each ele As HtmlElement In LikeBrowser.document.All
            If ele.GetAttribute("src") = "<image url>" Then
                ele.InvokeMember("click")
            End If
        Next

however, it never executes the "ele.InvokeMember("click")" statement (i tested that via putting a message box in there). I'd use the alt, but letter in the webpage there's an element with the same alt, so it invokes both & the other element causes a popup. I also tried using:

For Each ele As HtmlElement In LikeBrowser.document.All
            If ele.GetAttribute("alt") = "LIKE" and ele.GetAttribute("width") = "62" Then
                ele.InvokeMember("click")
            End If
        Next

but that gives the same result as using the src (it doesn't ever execute).

Can anyone help?
