Is there any wp plugin or code solution for EDD auto image resizing and licensing?

Hello,

I’ve been working on an online multi-vendor stock photography store which uses Easy Digital Downloads for stock photo ecommerce and Mayosis theme by Teconce. Currently the vendors have to upload different sized images for different licenses (Small, Medium, Large, etc) and also a different image for thumbnails.

But, my client wants solution where the vendors can upload only one image and it automatically resizes into the predefined resolutions, while adding new product.

Is there any solution for this using a plugin or code?
I would highly appreciate any feedback.
