Is there any easy way (via extension) to modify the "src" attribute of 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.
Thanks,
