SubCatagory Images and resize

[Guest]

How do I use the Catagory image on the first page of the sub catagory

 

example

 

but not on the individual subcatagory pages (the one in the upper right corner)

 

example

 

Or make them resize better so that you can actually read them? :(

 

Any direction would be greatly appreciated.

 

Thanks
