Image Upload Hack for Multiple Images?

I dearly, dearly need to be able to upload multiple images at the one time from the write page.

Can someone (pretty)please steer me in the right direction.

I want to keep things as absolutely simple for my users as possible and do not want them to ftp their images.

Nor do I need them to be able to edit and refine the images.

Nor do I need thumbnails in the posts, just the images.

All I want is for them to be able to upload more than one image at a time.
