FR: Share image via drag and drop
Second easiest way to share a screenshot is to drag and drop an image -- whether a file or an arbitrary image object. Letting users drag and drop non-file image objects also lets them avoid the need to save the image to local storage and later delete it manually.
Please allow this method of sharing an image via HTTP File Upload.
Of course, after the user drops the image, please let them confirm that they actually want to upload.
