Summernote copy image

I haven't found anything about this anywhere. How can I copy a selected image into the clipboard? I have created a custom js that adds a button to the popover of the image which works fine but I'm stuck here:

$.extend($.summernote.plugins, {
        'imageCopy': function (context) {
            var self = this;
            var ui = $.summernote.ui,
            $editable = context.layoutInfo.editable,
            options = context.options,
            $editor = context.layoutInfo.editor,
            lang = options.langInfo,
            $note = context.layoutInfo.note;

            context.memo('button.imageCopy', function () {
                var button = ui.button({
                    contents: options.imageCopy.icon,
                    container: false,
                    tooltip: lang.imageCopy.tooltip,
                    click: function () {
                        var img = $($editable.data('target'));
                        console.log('copy image=' + img);
                    }
                });
                return button.render();
            });
        }
    });

So I don't really know how I can get the data from the currently selected image and put it into the clipboard.
