Updating raster set

Q: When you add new jpegs to an existing raster set, can you remove the existing raster images from the list of source images in Raster Loader. Or will this remove them totally from the raster dataset.

A: When adding new images to an existing raster set you have to provide Raster Loader with the complete set. Due to complex nature of the pyramid created by Raster Loader it is impossible to update existing pyramid by simply providing additional images. In essence update does not differ in its operation from creating new raster dataset. So a short answer to your question would be: Removing existing images from the list in Raster Loader will remove them from raster dataset as well.
