For some reason I remember the powerstore product section loading a preview of the image you have just chosen giving the user visual feedback prior to submitting the current page.
I know the file manager exists for the content sections of the site, so the user does get to see the image in that instance, but I have seen this preview feature across a few sites.
I just found this as an example which I think is really nice... however, to protect their server it displays the 'Fonze' rather than your selected image!
