Hi, Perhaps the following example points in a useable direction: http://gis.ibbeck.de/ginfo/apps/OLExamples/OL27/examples/ExternalGraphicOver lay/ExternalGraphicOverlay.asp
I use a pointFeature styled with ExternalGraphic as Image Layer. With the style options one can change the image width, height and rotation. And the image is dragable through the DragFeature Control.
