In magento Default Setup when we click on
catalog >> Manage Categories
and go for editing any category then we found "Image" and "Thumbnail Image" File upload button.
When we upload image for "Image" Button that image display in Category Page above product listing.
But when we upload image for "Thumbnail Image" it is not display on category Page.
Where is magento display that Thumbnail Image in default set up. I want to know that.
