Advice on RSS feed creation required please.

Hello,

We are in talks with a large media group who would like to take our news articles via RSS and place them onto their sites. Due to the number of photographs within our articles they have suggested that we have one image at the top of the post, the text and then if possible a gallery/slider at the bottom of the pages, the gallery/slider should ideally display a single image that their readers can use to scroll through the rest of the images. They would like the content and image slider to appear within our feed so that it automatically displays the same on their site.

1. Is this possible?
2. Is there a simple WordPress image widget that will automatically take the images uploaded to that post/page and create a slider/gallery that can be operated from within the posts icons (MCE).
3. If it is possible, can the existing WordPress Feed Generator perform this?

I hope that someone can point me/us in the right direction.

Thank you
Paul
