I'd like to know how to resize the height of a background TD. A good example would be for the "Pook: Product Announcement" template here on Litmus. I love the beginning of the email using the background and overlapping text/images.

I tried to tweak the code of that part to make the background cell be shorter (or larger), but I've had no luck. At best, I've been able to change the size of the image, but the cell height remains, which doesn't achieve the results I'm looking for.

Anyone have any suggestions? Thank you in advance!
