HTML5 et CCS photo display problem !

Hi,

I develop my e-commerce site using DREAMWEAVER CS5.5 using HTML5 and CCS

My site directory is positioned in WAMPSERVEUR 2.2 and in the "www"

My local server is configured and it works

I start my program HEADER HTML5 and the CCS I realize my layout and the: background: url (.. / Img / header / logo.png) no-repeat; I incorporate my logo.

I record everything and I view my work and now I have only my texts appear, as well as the title of my logo, but not graphics

Here is my HTML: <a href="index.html" title="Test.com">

                            </ a>

                           <div classe="side-logo"> </ div>

I am looking for someone who could help me, so that I can continue to make my site

greetings

See you soon

Bruno
