Cache: "No Data" Tiles in areas not covered by Imagery

We have aerials obtained in 2010 which cover our entire muncipality and aerials from 1969 that only cover a portion or our area.

I have published both the 1969 and 2010 SDE raster datasets as map services and have generated map caches.

What I would to do is have the 1969 return a "No Data" tile in areas covered by the extent of the 2010 imagery but no imagery exists for 1969.

I have placed the "missing" and "blank" PNGs and JPEGs in my 1969 cache directory, but it is not working as I would like.   I have tried to cache the map
service to only the extent of the 1969 data or to the full extent of the 2010 data and neither works.


Any suggestions on how to accomplish this?
