This code show how to create a very simple drop shadow effect to all images with a given css class.
First give the images you want the shadow for the class “contentimage”.
Then some jQuery:
$('.contentimage').wrap("<span class='wrap1'><span class='wrap2'><span class='wrap3'></span></span></span>");
Then some css:
.wrap1, .wrap2, .wrap3 { display: block; }
.wrap1 { border: 1px solid #DDD; }
.wrap2 { border: 1px solid #BBB; }
.wrap3 { border: 1px solid #999; }
