Ok this is very strange,

Im trying to change the layout of my page and giving my sub categories big images. This has worked however for some reason when clicking through that category, its image still remains really large. I want this to shrink down and the subcategories to be bigger.

Please help :) Ive tried playing with settings

Small Image Width 100 Info
Small Image Height 80 Info
Heading Image Width - Admin 57 Info
Heading Image Height - Admin 40 Info
Subcategory Image Width 250 Info
Subcategory Image Height 175 Info
