Align images center in event overview

I’d also like the images to have a uniform size. The Pinterest layout does not solve my problem

You will need to add some additional CSS

This should make the image image sit at the top full width

.qemlistright {  max-width: 100%;  width: 100%;  height: auto;  overflow: hidden;}

As the two images you have are different proportions you could use CSS to equalize them in proportion ( although often just editing them in an editor may be more satisfactory as you have more control where to crop ) example CSS could be

img.qem-list-image {
  width: 300px;
  height: 150px;
  object-fit: cover;
}

How did you get on?
