Vb.Net Object on top of another

In VB.NET I made a web browser and I wanted there to be an image behind the web browser slightly peeking out. I put the image on after i put the web browser on the form and I cant get it to be behind the browser. Can anyone tell me ho开发者_JAVA百科w to do this?

right click the picturebox in the designer and select 'Sent To Back'

Alternatly, right click the webbrowser control an select 'Bring To Front'

Wouldn't it be simpler to edit the image to only have the part that is "peeking out" and place that on the form in the appropriate spot?
