bigger imager on eventview

@stevent:
in ugenda.nl you have two different width of datimage: the flyerimage and in event the same much bigger. I like that
My question is (not for developing JEM but) for my own site with JEM: How did you made this difference? (When I change width in general options, all images in all views have the same width. (except other imported images in descriptions)

I did a template override and inserted the large image, in stead of the thumbnail. I've set the width to 100% and the height to 'auto'. This makes the detailpage of an event more responsive, So the large image isn't off the screen on a small device like a smartphone, and the image is always over the full width of the text, even if the original is smaller. JEM doesn't resize the large image when you upload a file, it only creates a resized thumbnail. [feature request! ]
