no idea how to theme this layout

Anyone Please help MEEEEEE … I am sad

You can add three queries(one per category) and use the following CSS float:left; width:33%; to the wrapper divs.

You can use the code from this article.

eguru, yep you need to add thumbnail support to your theme, In the link alchymyth gave you it says it all, look for the part where it says to add code to functions.php

Thanks a lot freesouldesign. The trick you have mentioned worked like a charm.
@alchymyth- thanks a lot for the information ??
