Using jpgs for my images. What files are absolutely necessary, in other words are the .aux abd .jpg.aux.xml needed. I know the rrd is the pyramids which I dont care about. I know that the jpg, jpgw and xml are needed for the referenced and spatial reference. I cannot find a clear answer in the gis help.

Thanks

From ESRI: If you delete the .aux.xml file, you will lose all the information stored within it, including the transformation, statistics, and histogram information.

So if I just delete the pyramids (for size) rrd file will that corrupt the raster in any way. **It created pyramids in the mosaic even though I told it not to under environments, but that's another forum topic.** I dont need to do statistics on this image. The help says the aux looks for the pyramid file but does not say what happens when it is not there. I should say this is how I have been working on several rasters - deleting the pyramids only for size - just want to make sure they will not become corrupt sometime in the future.

Thx

I've deleted the rrd files in the past when they accidentally showed up and had no problem doing that.
