Hello Gabriel,

What you have to do is to hook "Initialize" client side event:

<

ClientEvents Initialize="wivInit" />

Then define your handler like this:

function wivInit(webImageViewer, eventArgs) {
 //webImageViewer.get_element().style.position = "absolute";
   webImageViewer.get_element().style.marginLeft = "400px;
}

get_element() method will give you reference to the DOM element of WebImageViewer. Then you can do anything with this element's style. you can change positioning, margins, padding, left position, top position. Anything that can be changed via JS DOM reference element.

Hope this helps.
