ID on IMG tag does not work in NN4 at all. Besides, what is 'clsItemPic' 
exactly? Should be the NAME of the image to work properly, so you already 
have the NAME/ID. Or is it a class? Then it won't work.

Generally, to get the ID of an item you're almost correct:

varImgSrc = opener.document.images.clsItemPic.id;

You don't need the eval and id is a property of the object itself, not of 
the style. 'window.' is not necessary but won't hurt either.

But I don't think this is going to work on images in NN4.
