// Sanity check: query_db_index is where we will lookup detailed infos like
// the file name later, when printing out matching images. This database
// must be the same as the one used for image registration.
// However, if the image set has been created using a subset of a
// database (using -i0 -i4 -i6 ...), img_set->num_images will be less
// than the number of images in the db. Without a database ID that's
// stored in the image set, we cannot realiably check that condition.
