On the category pages I have succeeded in moving the descriptive text so that it appears after the category image and the sub-category listings.

Now I would like to style the page so that the category image aligns left and the sub-category listings align right with the text below, but so far I've not been able to move those elements at all.

Here is an example category page: http://www.broadwayfloral.com/weddings-c-34.html.

Ideally I'd like to have two columns of sub-category listings to the right of the category image.
