images 40px wide

Hi,

 Whenever I add an image, for example with ^h ^i, Amaya inserts something
like this:
<img alt="qqq" src="qqq.jpg" *width="40"*>
and I have to delete the width property.

Is it possible to change some configuration bit so that Amaya does not add
any measures to the images?
It's Amaya 10.1 dated April 29 in Windows XP.

Thanks!
