Of course, another attributes may be there.

I am confused. I can not figure out how to create the following as HTML 
export result:

<img src="img.png" alt="An image without :width 600 attribute">

Attempt to add quotes leads to &quot; and does not prevent ":width" to 
become another attribute.

   #+attr_html: :alt An image without :width 600 attribute
   [[file:img.png]]

   <p><img src="img.png" alt="An image without" width="600 attribute" />
</p>

My current variant:

":\\(?:[^\n]*?[[:blank:]]\\)?:width[[:blank:]]+\\(\\S-+\\)"

The regexp should not match e.g.

#+attr_html: :alt something
:width 600

P.S. I would prefer to use the same parser as ox does.
