Hi Ryan, my Mediabox popup is set to 88% witdh and height. The images therein should fit into this frame - at the basic setting using the standard theme, images are stretched to 100% width and if upright, the bototm cut off. I am using this in my css:

#jcemediabox-popup-content > embed, #jcemediabox-popup-content > img, #jcemediabox-popup-content > object, #jcemediabox-popup-content > video {
  object-fit: contain;
  max-width: 100%;
  max-height: 100%;
  width: auto;
  height: auto;
  margin-left: -25%;
  padding-left: 50%;
}

but it does not work for all images... Please take alook here: https://live.franzkmail.de/weblog-uebersicht.html

I just realized: the marketing team has me fooled - the CSS works as expected, but some of the large images are not quite large enough 😃 - I assumed the image size would always be too big, as they use images from all over the place...

Anyway, is there a better way? Ideally, the medaibox would shrink if content is physically too small.
