IOError: cannot write mode RGBA as JPEG

[Luke Duffy]

Hi All

I am trying to upload images for the corresponding products through the Oscar admin panel.

The UI reports no error. 

The image appears in the folder /edx/app/ecommerce/ecommerce/media/images/products/2017/08 as expected.

I have the following log entries:

Any ideas ??

Thanks
