thank you for your reply

hi i have found a solutions hand of openlayers.

OpenLayers.Util.onImageLoadError

will help you with you not have baselayer image on your app...

I'm not really sure to understand your needs but:

If you're looking to add a logo after a certain zoom, you could create a layer that only appears from a given zoom with the embedded image in it. Some WMS layer should do the trick.

If you do that because you have nothing to show after level 12, then you should just limit your zoom to a certain amount.
