I've got a website http://jazztravels.com. During my site, the house page has images loaded from the custom publish, Nevertheless the images doesn't appear to load in FF although it works perfectly fine in IE.

I observed that display:none is put into the look tag, which isn't contained in IE. However am not able to recognize why this really is added and just how it may be prevented.

Any help could be greatly appreciated.

it appears, you have spaces(' ') inside your path names. You need to take them off, as FF and IE handle them in a different way.

In FF I visit a request: http://jazztravels.com/wp-content/themes/Doubtfire%20Wordpress%20Theme/css/colour/images/shine.png
