Issue 124 Added max-width styling to img tag in response to Image on eve...

The image trimmer object alters values on the image model directly. When an event is edited and saved there is not done any validation checking if the image trimmer has completed altering the values. 

This bug should only apply to a small group of users since the user in most cases will spend enough time on the edit page for the image trimmer to complete loading.

Instead of adding code to save the original values of the image model and restoring this I've added a CSS style to the image tag which should force the image to stay within the bounds.
