E10 adding white space on top of footer image

I've been trying to create an email that has a white textbox in the middle, surrounded by images on 4 sides (which was one image, sliced out). I've included the email below

http://app.na.agcocorp.com/e/es.aspx?s=1524474208&e=697&elq=6d4fc785f9a74a2ab3c46566bfbb0908

Anyways, no matter what I do, the email seems to add a 30?px whitespace between the two side images and the bottom image. Everything was aligned within Eloqua. I even tried to create a text-box and use the following code for the bottom image:

<table border="0" cellpadding="0" cellspacing="0">

<tbody><tr>

   <td> <img elqtitle="" src="http://images.na.agcocorp.com/EloquaImages/clients/AGCOCorporation/{1ca5dc18-f6cd-4abe-a72d-23d0065e74c0}_PTS_FieldCheck_Footer.jpg" style="display:block;">

</td></tr>

   </tbody></table>

Still have the same problem. It shows up fine in Firefox/Chrome, but when actually sent via Outlook or Gmail, the whitespace shows up

Any ideas?

Thanks!
