Hi!

I have a problem with Post Featured Image size. When the image is a bit too small, it's shown too big.

 I already set the Featured image thumbnail height in the Laborator settings to 500px. However when an image is smaller than that, it just stretches and it's very noticeable the fact that it's a low res image.

Here's a post where the image is displayed correctly: first post

Here's a post where it's not: second post

Is it my problem, not uploading images high resolution enough?

Thanks in advance
