Adding a Size Chart Image to Products in Selected Category?

Aloha,

I have a category called Hawaiian Shirts and in that category I have 25 shirts and would like to add a size chart under the product images.

Now I know I could add another image that is the size chart but dont want that.
I know I can add the size chart to each product in the description but I dont want that either.

I guess I want a program solution that if I want to add a size chart to a specific category I can do it all at once.

Thanks!

A very quick solution would be

1) To use the category image as your size chart.
2) Not show the category image in places where you do not want it to be seen..maybe in list of categories etc
3) make the category image show up in the product detail template
