thanks for the info
but the second part of post refers to adding an image in place of a category text) I did as you suggested and the image appears in the category after it is selectedin the main page

I guess my question is first how to replace the category text name with an image like a button (something more graphical than text ) but most important , how can i put the categores in the middle pf the main page not just the side and use an image the customer can click on to get to that category thanks
