ImageUpload user experience #693
Description
The ImageUpload component currently requires a width and height to be specified to start cropping after the user selected an image. What I would like to see is that the ratio is optional. If the ratio is not specified, cropping should not automatically be started after selecting the image, but the user should be given the option to crop it. The cropping should then display the entire image and be something where a selection can be made on the image, instead of moving and zooming the image within the cropping view, as the ratio might change when there's none specified. This way, the ImageUpload component could be used for WhatsApp-like implementations.
