 1. The Image Gallery tool can be configured to collect data about images/videos as ingest runs or all at once after ingest.  To change this setting go to "Tools", "Options", "Image /Video Gallery".  This setting is saved per case, but cannot be changed during ingest. See the Options window for more details
 2. Create a case as normal and add a disk image (or folder of files) as a data source.  Ensure that you have the hash lookup module enabled with NSRL and known bad hashsets, the EXIF module enabled, and the File Type module enabled.

 4. Groups of images will be presented as they are analyzed by the background ingest modules.  You can later resort and regroup, but it is required to keep it grouped by folder while ingest is still ongoing. 
 5. As each group is reviewed, the next highest priority group is presented, according to a sorting criteria (the default is the density of hash set hits).
 6. Images that were hits from hashsets, will have a dashed border around them.
