The whole point of having an imagemanager is that totally unskilled users do not have to be bothered with uploading images themselves, but that they can choose from a selection of images ready for them. And not just them, for everyone. This means that you can give a few users access to the upload feature of the imagemanager, and give the rest a break, and let them select the images from the controlled imagemanager.
However, Catz has made the uploader avialable through his mydownloads RC1 hack, you could try and incorporate that into the news module.
