Bug in HTML Code Output

Hi,
I noticed my wpml flags code was in red when I look at the HTML which seems to be due to some bugs in the code.

There are 2 height tags output and extra set of opening closing commas around the 2nd height tag as follows:

<img class=”wpml_flags” src=”mydomain/path-to/flags/ar.png ” height=”12″ ” height=”18″ ” alt=”ar” width=”18″ />

This is a great plugin and it would be great if I could fix this error!

Thank you.
