EE Multiple Image Upload

Hi, here's what I need. We presently have an expression engine 2.4.0 website that has a gallery that works as follows Each Image for the Gallery is published as a New Entry (this is because each image has a lot of information assigned to is, eg. Title, Related Articles using "Playa", Other Selections etc) . The problem with this is that we can only upload 1 image at a time! What we need is to be able to upload multiple images in one upload, they would all go into the channel "Gallery". If the basic fileds of the group upload can be set too, eg. When I upload 20 images all have field1, field2 and field3 completed too
