Juergen Hasch's 15 lines of Javascript code to implement "paste images directly from the clipboard (e.g. screenshots) into the notebook" for Chrome. Slow as hell for anything larger than some 10k.

window.addEventListener('paste', function(event){
    var cell = IPython.notebook.get_selected_cell();
    var items = event.clipboardData.items;
    for (var i = 0; i < items.length; ++i) {
        if (items[i].kind == 'file' && items[i].type.indexOf('image/') !== -1) {
            var blob = items[i].getAsFile();
            window.URL = window.URL || window.webkitURL;
            var blobUrl = window.URL.createObjectURL(blob);
            var img = document.createElement('img');
            img.src = blobUrl;

            var reader = new FileReader();
            reader.onload = ( function(evt) {
                var new_cell = IPython.notebook.insert_cell_below('markdown');
                var str = '<img src="' + evt.target.result + '">';
                new_cell.set_text(str);
                new_cell.edit_mode();
                new_cell.execute();
                } );
            reader.readAsDataURL(blob);
        }
    }
});
