The problem is that you try to resize the page immediately after it is 
requested (and before it is finished loading). In NN4, the document.images 
array does not exist until the page has been completely loaded, so when you 
ask about an image it says the image is not (yet) present.

If you want this to work in NN4, put the resize script in the popup page and 
execute it onLoad.
