CSS max-width autoresize not working for height resize

Hi guys i am using the css max-width to auto resize the images in wordpress post but the images are not properly autoresized that is only the width is resized and not the height.

How can i have a autoresize both of the width and height of the images?


.postclass img {
max-width: 500px;
width: expression(this.width > 500 ? 500: true); }

 

.postclass img {
max-width: 500px;
max-height: 500px;
width: expression(this.width > 500 ? 500: true);
height: expression(this.height > 500 ? 500: true);
}

Try that.

 

nah that will make the image look like a monster..lol
its called autoresize not max width and max height

 

Try using:

width: auto;
height: auto;
