Image widget for images hosted in the cloud.

[dindinet]

Hi Just had my first play with netlify-cms
We like to host all of our images in the cloud and not in the site repo.

The image widget want s to upload a local file but i want to add a url to my cloud hosted image.

I changed the image field to use a text widget which allowed me to enter the url but the
preview of course does not display an image.

Is there a quick change to the image widget that could make it possible to use a url instead of uploading an image?
