To check if a file exists I wrote my own viewHelper which then can be 
used (basically) like this:

<f:if condition="{my:file.exists(path: '{image}')}">
	<f:image ... />
</f:if>

You could also write your own image viewHelper to which you could 
provide an error message or a default image:

<my:image src="" fallback="" errorMessage="" />
