Display only image and background in portal

Hey guys it's me again. I want my portal to display only an image, and disable the forum header image and everything. The image below should explain it all.

What image? 

Do you mean like a loading page?

jesus, what a nob I am forgetting the image! Sorry, ye this is what I mean

As long as you're okay with displaying a link to Forumotion at the bottom...

Just make a HTML page, and use the following settings:

"Do you wish to use your forum header and footer ?" > No
"Use this page as homepage ?" > Yes

In the body, place the following code and insert your image and link into the appropriate places:

Code:

<br /><br /><br /><div id="welcome-button" align="center"><a href="http://premierhax.forumotion.co.uk/"><img style="text-align:center;max-width:50%;height:auto;display:inline;border:0;" src="https://s13.postimg.org/ru2cbfgmf/cooltext235347918754335.png" /></a></div>
<br /><br /><br /><br />
<div id="footer-link" style="text-align:center;font-size:10px;"><a href="http://www.forumotion.co.uk">Free Forum</a></div>

Here is what it looks like: http://prntscr.com/eirnqc

It lacks the glamour; however, if you want to style it some more but don't know how, then please ask.

If you do not use the forum's header and footer, you have to have a link to Forumotion.

Yes, this is important to note in the code displayed:

Code: <div id="footer-link" style="text-align:center;font-size:10px;"><a href="http://www.forumotion.co.uk">Free Forum</a></div>
