14775	Image Widths set to Auto in style.css of Twenty Ten theme	rfair404		"Twenty Ten sets image width and height in style.css line 762. 


{{{
#content img {
	margin: 0;
	height: auto;
	max-width: 640px;
	width: auto;
}
}}}

When I use Twenty Ten as a parent theme, this attribute causes my child theme not to pass Theme Unit Testing - Images Alignment Test. Specifically the Centered Image with Caption and Wide Image, Resized In Editor sections. 

Suggest removing line 764 and 766 of style.css
