Is there any easy way (via extension) to modify the

images on wiki pages?
I see hooks for modifying href values - LinkBegin and LinkEnd. But I
don't see something similar for images, whose URLs seem to be produced via
File::getUrl().
Purpose: I want to add a querystring parameter onto the ends of the URLs,
turning <img src="foo.jpg"/> into <img
src="foo.jpg?timestamp=xxxxxxxxxxx"/> to aid with caching.
There's not a great hook point for this I think, but you could probably add
one in.
ThumbnailImage::toHtml() in includes/media/MediaTransformOutput.php is the
function that actually produces the <img> tag. You could probably stash
something there, or on the constructor for the class, to modify the URL.
