A Working Enter Button, but no image, just a square white box

I’m trying to use image locaenterbutton.jpg for an enter button and on page when I test it in my browser, I just see a white box.

What 'am I missing?

This is my entry below.

<td><input name=“myBtn” type=“locaenterbutton.jpg” src=“Custom Image Button Src Goes Here” width=“88” height=“436” style=“width:88px;height:36px;padding:1px;margin:0px;border:none;” onClick=“javascript:ajax_post();”></td>

Thanks, Scott
