Category pics are HUGE...... need to shrink them

[Guest sushiboy]

Hi

I uploaded my category pictures and each single item pic takes up half the page.

I resized one to a smaller version before I uploaded it and when it displayed in the store... it was

black and white.

My "product" images seem to be fine.

Is there something that needs to be edited in the script to have them automatically resized upon upload?

Is so,... can you put the path to that file?

thanks
