Popup size doesn't match image size

[Sven74Muc]

If I click on a marker the popup opens. If the image is bigger than the default popup size. The issue happens like in the screens shown. If I close the popup and open it agin, everything is ok.
This happens because first the popup will be called and then the image. At the time the popup is called the first time the popup does not know the image size.

This needs to be handled with:
listen for the image's load event and call the popup's update() method once it has loaded

This in theory... I'm not a programmer, so don't know now how to go ahead.
