relative file path to image URL/background images/other pages in the site NOT recognized consitently over pages

Hi,

in my web site I encoutered an overall problem with stating the right relative path to images and/or URLs they are incosistent - path to an image in the master page file like (or in the related CSS file):


background-image:url(Website/images/side_frame.jpg);


it will not load on all pages - why's that?
the same with relative URL paths su as:


<a href="Content/Help/Get-started.aspx">

I used different prefix combination such as: ~/ or ../../  but the it solve the problem on one type of page and create another

Any advice?

 

Thanks
