Featured image changes

extra field: upload a featured image.
The featured image will be displayed in the widget (smaller) and on the event list page.

the images are floating next to the date:

date - image - event details

They are floating like this on the event list page as well as in the widget,
Depending on the design of your theme: they will have to have room to
float!

I was thinking of making a responsive version, but it all depends how (responsive) the theme is set up
