Problem with width auto in chrome

I dont know since when i have this problem but if you go to www.lacestamagica.com surfing on chrome, the width:auto sets the width to the 100% and brokes image dimensions, you can see it surfing on ie or firefox, any help?

Ok i found the problem and i left the answer if anyone has the same problem. if you set max-heigt:x px; and width:auto; you need to set height:auto; for chrome to redimension the image in proportion.

What css file did you edit to achieve this?

I usually use yootheme so i do it in my custom.csd but you can do it in the hikashop frontend css wich can be modified in configuration display
