I think so. Why should a data uri image be different?

I also think so because IE, Firefox and Opera 8 fire a load event for
that. Opera 9 doesn't though, but it should.
If that's not a good enough reason to fire a load | error event:
Say if you do img.src = img.src and the image is no longer at the
address and is not cached? You'd want it to fire an error event
Also img.src = img.src doesn't fire an onchange event ( not saying it
should ) so you can't use that to tell if the img.src setter was used.
I guess you could use setAttribute and check for the attribute to be
modifed, but that still doesn't tell you when the image is fully
loaded or not.
That's my take on this.
