I googled and came up with this post.
http://www.ezportal.com/feature-request/center-left-and-center-right-blocks/msg730/#msg730

Does anyone have a coding solution for this?

Idealy I'd like to have 2 distinct "center" blocks to use but I can settle for any type of split that allows for content to be shown in the left-center half and right-center half.

Thanks for you time!

Here is the coding for the media block.
"
global $sourcedir, $user_info, $ID_MEMBER, $context, $txt, $galurl, $galurl2, $scripturl, $settings, $db_prefix;
loadLanguage('Aeva');
@include_once($sourcedir . '/Aeva-Subs.php');
echo aeva_listItems(aeva_getMediaItems(0, 4, 'RAND()'), false, '', 4);
