A friendlier error message

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a document
2. Insert a bitmap image (either via Common Shape, or drag-and-drop)
3. Save and close the document
4. Rename the source bitmap image (or move it to another directory)
5. Open the same document

What is the expected output? What do you see instead?
EXPECTED: A human-readable error message telling me that "One or more image
files used in this document have been moved or renamed."
ACTUAL: A wall of stack trace describing a javascipt error


What version of the product are you using? On what operating system?
1.0 standalone on Windows XP Pro SP3


Please provide any additional information below.
Additionally, some kind of visual cue to indicate that an image is missing
would be nice. Maybe default back to the image placeholder that appears
when you drag a Bitmap Image shape onto the page.
