+    from StringIO import StringIO
+
+    photo = Image.open('/path/to/file/image.jpg')

+    height = int((float(photo.size[1]) * float(wpercent)))
+    photo = photo.resize((basewidth, height), Image.ANTIALIAS)
+
+    image_io = StringIO.StringIO()
+    photo.save(image_io, format='JPEG')
+
+    # If you do not seek(0), the image will be at the end of the file and
