Hi,
I have put in a modul on the a page with three images, two of them are 544 x 544 pix, the middle on is an image 1088 x 544 pix, double width but same height. The columns in this row is 3+6+3. Page made with SP SiteBuilder Pro.
I have used <div> and </div> in the html editor to avoid the extra space when using <p> and </p>, but still this image appears with a larger height (313.333) than the other two images (298,667).

You will see the issue in the bottom of the start page:

Some automatic settings issue here?
