[OpenLayers-Users] How to make a drag and drop for markers?

[Jimmy Aumard]

Thanks it's perfect for my application!!!

I just have to develop that :s

I have one question : It's possible to put an offset to the external
graphic? Because images of markers (marker.png) are centered on the center
of the image's marker and not on the bottom of the image's marker

I'm not sure I'm clear but it's difficult to explain this in English for
my...  Sorry


Cheers

Jim
