Hi @mrsnewbie, thanks for your patience. I checked the site and looked at the site design and in the published mode, and the styling looks the same to me:
I believe the issue may be in the structure, how this elements are setup on the page.
It looks like you are using columns with a link block set to be absolutely positioned over the column and image. Since the link block is absolutely positioned and the image is not, the images are resizing as the white space increases or decreases, but the resizing is uneven.
I would highly recommend to change this to put the image inside the link block which will cause the image and link block to resize evenly.
I hope this helps, let me know if you have any questions.
