This is my hack. 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);
}
}
});
