I corrected in style.css, as it is in the bender theme, ie this img {max-width: 100%? width: auto; height: auto} in this img {max-width: 100%; width: auto \ 9; height: auto} and everything works fine.

I do not see difference, not sure what \9 and ? means there..

I do not know what it means, it's  in the bender theme that's why I put it. It works well. Is there another solution?

@kriskoyk
I would say that is invalid css code.
I would change:
img {max-width: 100%;width: auto;height: auto;}
into:
body:not(.page) img {max-width: 100%;width: auto;height: auto;}

I do not think the solution you propose is better. The other (img {max-width:100%;width:auto\9;height:auto;}) that exists on the other hand in the Bender issue is probably better.

@kriskoyk
width:auto\9 is invalid attribute for width, so if you believe to have error value that does nothing is better, than it's your choice.
