Handling Thumb Sizes

Hi,

We love this theme!!

The only problem is when we add new elements with the TD Composer with new thumbnails sizes we need to activate that thumb size on the panel, but then they almost never fit and there is a white space on the right or at the bottom of each thumb.

Any way we can make all the thumbs fit any new element we choose to add the pages without re-uploading resized images of the featured images?

Any “push button” solution to resize and fit all images on the site?

Thanks!
