OK, I see from the link you PMed me that the button says Contact Us (translated). So just to clarify:
1) you want a link to another website?
If so, you definitely don't want the form, but just a link, like this:
<a href="http://othersite.com" class="something"></a>
You could style that link to look like the button now. You can do it with CSS and no image. We can help you with that.
2) Out of interest, why do you want an external link for contact purposes?
