I have recently set up a featured image for some of my posts, but this theme is resizing the pictures to the posts' width and what seems like a constant height.
Here's what it looks like: http://s1.postimg.org/v7b2be2gv/Capture.png.
Is this default behavior? Can it be changed so that original images are displayed?
This way it either looks bad or requires additional work by me to fix it, and frankly I'd rather have it just work.
