Poloray Blog Page Image Thumbnail Stretched

Hello,
I have a blog page that contains blog entries that sometimes have an image. On the actual blog post, the image thumbnail shows at the correct size. However, on the blog page (with the listing of all the blog entries) the image is stretched wide and looks funny. Could you help me with some other code or method to get those images looking correct?

Here's a link to the blog page for reference: http://www.prrcd.org/conservation-connection/
Two examples of stretched images are under the entries "Iowa Agri Women Policy Conference" and "Observe Lincoln Highway Centennial Day on October 31"

 

Hello,

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.postimg {
width: 200px!important;
height: 200px!important;
}

Adjust its value as per your requirements.

 

Worked perfectly! Thank you!
