I have created a mosaic dataset and added rasters in it.
Then I published it as image service. I used query method to display all records of my dataset.
But when I try to view raster image of any of the object id using "Export Image" method, a gray/black image comes instead of the correct image. The thumbnail is displayed correctly.
I am using the following URL to view the image

I have also attached the snapshot of the same.

Need help to resolve the problem.
