Google Earth: I want to fill a polygon with an image, not a color -

my question simple: possible fill polygon in google earth image file (bmp, jpeg, gif,...), instead of color?

thank you!

i had same issue , found model solution suggested pablo reyes best. problem ground overlays expect image plate carrée projection. if image orthographic projection, trying compensate using <gx:latlonquad> distorts image because applies non-affine transformation. plus altitude coordinate of <gx:latlonquad> ignored anyway, image curves globe maintaining constant altitude.

the kml sample provided pablo reyes good. without need sketchup, model.dae file flat plane looks like:

where plane 1000 meters square model coordinate system origin in center. defined by:

<float_array id="id12" count="24">500.0 500.0 0 -500.0 -500.0 0 -500.0 500.0 0 500.0 -500.0 0 500.0 -500.0 0 500.0 500.0 0 -500.0 -500.0 0 -500.0 500.0 0</float_array> 

the image applied plane edge-to-edge. if image not square, dimensions of plane must modified accordingly. plane can re-sized , rotated in ge using <scale> , <orientation> kml settings. , opacity of image set by:

<color>0.3 0.3 0.3 1</color> 

this allows me use same model file multiple images have different sizes, locations, , orientations (as long have same shape: square in case). , renders orthographic projections tangent globe in center.
