Banners won't publish RW Version 5.4.1 (14041)

I’m using Overture theme - Brandon Lee

the pages publish but it only puts up a icon where the banner picture is. I’ve correctly labeled the banners and placed in the resources according to his theme tutorial as in banner_1.jpg and chosen the appropriate drop down under Styles. It shows up fine in preview but won’t publish correctly. I’ve sent an Brandon Lee as well.

I’ve searched in google and it may be something in the cache (I’m not meaning safari or chrome) but I couldn’t find under RW settings how to cache bust. Thanks for your help.
