Wondering if anyone can clear this up, my background images show fine in DW but when I press F12 to view in the browser they dissapear.

Let's see a link.. we can't diagnose anything just from your description, although it sounds like you may have some error in your code or something else missing. You should not rely on DW's internal preview for anything, it's simply not accurate.

The site isnt live yet so I can't send a link yet, anyhow been playing around with the image settings, I think it was something to do with the links being relevant to the site root and not the document. But they seem to be working now.

Kinda thought it sounded like a pathing issue.
