Ability to enlarge images on vacancy pages

Ability to add data in contentful to enlarge an image in a vacancy.
A quick fix for the problem is to make an image added to a vacancy width="80%" and horizontally center it.

Example: https://svsticky.nl/vacatures/software-developer-tester
For this vacancy the vacancy information is given on the poster, but this poster is to small to read anything from it. The original image has w=1701 h=2386. So it would be big enough to scale to a size that would make it readable
