Is it possible to have multiple category images?

Hi All,

I have a look to my website that I would like to implement but I'm struggling ... can anyone please help!?

When clicking on a menu item the user is given a page with the sub-categories + their respective images. When clicking on a category the sub-category image remains at the top of the page above my products or next level sub-cats.

I would like it so that once IN the category the image changes. For example, I would like a small image when looking at the categories as I have now but when in the category I would liek a wide banner type image to stretch accross the info pane.

My initial thoughts were to try and add something like the _LRG text string to the image file but on investigating I just don't see how I can implement it.

If anyone has any ideas on how this can be done I would be greatly appreciative.

For reference I am currently using Ver. 1.3.8a
