The summary of this bug is fairly bogus since there is already ways to purge the image cache.

Hmm... not sure how I feel about this.  The event name is very specific to the image cache, and yet the other event names are much more generic so as to apply to multiple observers.  Here, there is only one observer of the image cache because there is only one image cache.  Therefore, the observer service seems like the wrong way to build this API.  One alternative is to pluralize the observer notification (something like "content-flush-image-caches").  Another approach would be to add an API on imgILoader.

content-flush-image-caches?  Would this imply the we would dump the network copy of an image?

(or true depending on what you want to do).
