Image size on post lists, how to stop them from stretching ?

Hello,

I would like to know how to adjust the image size on the posts list. The post page itself is good, its the lists of posts within categories, etc.. that show a stretched image. How can i modify it so that it stops ?

Thank you !

 

Paste the following code in your custom css
Appearance -> Theme Options -> Styling Options -> Custom CSS

Code:

.content-bar .post .post_content img.postimg {
width: auto;
}

This will solve your issue.
