Do not silently ignore exceptions in image viewhelper
Exceptions that an image could not be rendered must not be silently ignored but thrown or logged in the production context
If you add for example this viewhelper
<f:image src="http://test.com/image.jpg" /> (yes that wont work but i also wonder why it is not possible to add a url to an image and then just render it) you'll get an
<img /> tag and thats it. No logging - no information about a broken image tag.
