If you load an image directly (i.e. outside a document) and go context menu / Properties you'll see that the alt text given is "The image “x” cannot be displayed, because it contains errors.". This isn't the most helpful for consumers of this information (most importantly screen readers). Obviously we can't tell what's in the image, but we should present what information we can in-case it's what was wanted. E.g.:

"This image has the filename logo.gif, is 276 pixels wide by 110 pixels tall and is a GIF"

If the image really is broken then maybe we can redirect to another page or programmatically write a proper error message.

Reproducible: Always

Steps to Reproduce:
1. Load an image directly
2. Right click on it and go to Properties
3. Note the contents of the alt attribute

Actual Results:  
Unhelpful alt text

Expected Results:  
Helpful alt text
