The ImageForeground uses glDrawPixels, the PolygonForegound uses a textured polygon, and the Geometry method uses a textured planar quad (in the Geometry). In terms of speed, I would think like Carsten that they are all bound by the image data transfer (geometry is a quad ;) ). The texture methods could be more flexible, by preloading textures for example ..
