How do you catch rendering errors in RPE?

Several of the DNG users have put the images into artifacts in DNG that do not specify the item is an image. Also, we have images that will not render.

RPE crashes during document creation.

What I am tryign to do is to gracefully handle the error, put text into the generated document that states, the error but completes.

I am NOT using <div> without modifications because several users put hyper links to word definitions and the WORD output document needs to have these stripped out.

I am getting a 404 error for some images

for the other. The <div> error is from an attempt to render an image that is not specified as a wrapperResource.
Summary:
1. How to catch these so RPE will complete
2. Will be to address the errors themselves.
Thanks,
