This also worked for me. Thanks, Richard.
My iPhone did decode it correctly, both the native camera and the
'Barcode to PC' app.

They could have provided a larger image. This is only 87 x 86 pixels.
Images I've generated are more like 123 x 123 or 171 x 171.
Note that the file size of mine is an order of magnitude smaller, 484
bytes v. 6457.
qtqr also failed to decode dierge_16.jpg.
