PLS HELP PLS HELP

Do you have a URL we can see?

www.slfobis.com

if you see the mainpage banner shows the but when u click the category SLIDER (for ex.) there is a empty space which is for image and wordings following to it...
pls help...

why don't you use the banner module or just include the <img /> instead of using <div id="whatever"> and code the include the image in css?. firefox will render <div></div> = nothing, fix problem is easy just type something inside the div tag that will do.

P.S your code are messy.
