then you need to assign a class to product images aka
<img src="myimage" class="product" ... />
and then apply the changes in your CSS to only images using that class.
Currently, you are applying it to all images:
img
{
background:url(img/shadow.gif) no-repeat right bottom;
padding:4px 10px 10px 4px;
border:0;
border-top:#eee 1px solid;
border-left:#eee 1px solid;
}
Once youve added the class="product" to your image tags, then you just do this:
img.product
{
background:url(img/shadow.gif) no-repeat right bottom;
padding:4px 10px 10px 4px;
border:0;
border-top:#eee 1px solid;
border-left:#eee 1px solid;
}
