Hi Sledge and welcome to CZ!

I just put this on a test site as shown in the link below. Is this how you would like it to show? Please keep in mind that SMF 2.0.17 is not mobile ready so it may not look correct on mobile devices. On my PC, it looks good but on my tablet it stretches completely past the right side of the header.
https://skhilled.com/smf17/index.phpIf this is what you wanted, as shown in the link, I've posted the code for it below. Remember, the code below shows the image in the same directory as the original logo... /images/id/:
#logo a {
position: absolute;
top: 7.3em;
left: 4em;
display: block;
width: 1200px;
height: 141px;
cursor: pointer;
background: url(../images/id/tpclogobase.gif) no-repeat;
}
