Help with categories_multicolumns.tpl

I added this include



{include file=“categories_pages/categories_multicolumns.tpl” categories=$root_categories}



(with no changes to categories_multicolumns.tpl)



to the welcome.tpl and the first day it worked find, but now all the category images don’t display. Checking the admin for each category shows that each image is still there.



Any ideas why it might not display
