[OpenLayers-Users] Declare a default externalGraphic

[Joao Duarte]

In the end of the file OpenLayers.Feature.Vector you will find the default
style for the features.
Just add a externalGraphic entry with your default image or make a patch
that does that.

Hope it helps.

This is what im trying out right now, but doing an additional sync ajax
call per feature is killing performance

Could you use javascript to check to see if the image can be accessed
and then set the symbol property based on the result?
