Allow to add images from external URL
Especially from mobile browsers downloading images locally in order to upload them in Gancio is a long and tedious process. It would be incredibly helpful to be able to insert images by simply specifying their external URL.
I think that it can be done on the client side, before to send the request for the insertion of the new event. The image can be downloaded locally with js and then send it along with the final request to the server.
What do you think?
