Ok here is a page I just setup that has one that is not the same size.

http://healthyrowan.com/test-page/

But it must have ben a javascript issue when we were having the issue. I recently updated and now its working better, but there is a size difference when the featured image is shown when the image is not landscape. Is there a way to lock it down so all of the images display in the same size just if its portrait then it crops the photo to fit in the parameters.

I have use many other templates that do a great job of this and it helps to standardize the pictures better.
