dojo.ready(function() {
dojo.query('img').forEach(function(img){
dojo.connect(img,'onerror',function() {
dojo.destroy(img);
});
});

@Karl Tiedt: Applied to a collection — very nice! I’ll keep that in mind from this point forward.
Would you happen to have code to do this with prototype?
I wish images would fire an event if they didn’t load then we could put something in it’s place instead of going through every image checking. Kind of slow…
