Rename filename in CommerceMedia Collection

Hi,

I am looking into the possibility of renaming some images that have been assigned to a product in episerver commerce.

As I see it the only way that I can achieve would I would like to do is.

1. Get the original image.
2. Duplicate the original image by creating a new instance and setting all the properties.
3. Set the filename.
4. Save the image.
5. Associate the image to the product.
6. Remove / delete the original image.

Seems alot of work to rename a filename.

Has anyone tried anything similar?

Thanks

Paul
