Unexpected appearance of image borders

Hi –

I just noticed the appearance of a border around some images, such as the logo and carousel images. I’m not sure how these got there! I haven’t added any custom CSS that would have caused this. I’d like to completely turn this off, but can’t find a setting for it.

Do you have a suggestion for doing so?

Please see https://lgp.webgnostics.net/lodging/condos/erin-hills-104/ for an example of the logo and carousel unwanted image borders.

Thanks,
B
