[1.5x] Buyers share images or youtube videos in product Page

In the product page of the front end, buyers can paste external image links(like they upload their product photos onto photobucket.com) and youtube video links then upload the links for admin's authorization.

Once Admin enable the links, their shared videos and product images are displayed on the top of the review section.
Admin can set in the backend how many reward points buyers get for enabled shared images or youtube videos.

I have seen many stores have this feature already... not too many, but some of them do have it.
I think those shared photos and videos help to motivate visitors to buy and the shared photos and videos let viewers off your sites know you are selling something and contributes to attracting more traffic to your site.

Maybe this is a good idea?

I know this thread is over two years old, but I would also like to see this as a feature or an extension. It would be great if customers could submit a photo or video for a product they own. My site has mostly custom products, with 7 design options for each. They are already sharing these images on FB, Twitter, Instagram.... which helps... but it'd be great if there was some way to tie photo sharing into the site.

Amazon has a Customer Media (/customer-media/upload/productID) which seems pretty straight forward. Would love to have this feature on my store.
