[OpenLayers-Users] Is there a way for OL to figure out that one of the layers is pink?

[Greg Allensworth]

You could catch the 'tileerror' event on the layer.
I think that tileerror is relatively new, but I may be mistaken.

It would go something like this:

layer = new OL.WMS(...);

layer.events.register('tileerror', null, function () {
    this.setVisibility(false);
    alert('oops!');
});
