Enable carousel Module changes heighth at will

We have a carousel configured that changes height at will. So when you refresh your screen it may be normal size, or large. I have attached images to show you along with module setup. Thanks.

You didn't set any thing in the height field of your module. So the images will resize for fit in the 250px width limit that you set while the height will be generated automatically based on the width and the proportion of the image.
If you want your images to have a fixed height in the carousel, then simply enter a value in the height field.

That corrected it. Thanks.
