When a Location is first created, it has a blank Logo Image. You can update the image from the Details > Edit view. When you download a new image file, it may not show straight away in the Image display. This is due to browser caching of any older image. If you got a success message, the image has been updated and will show after the cache has been refreshed.
When a Location is first created, checks are made to ensure that it is given a valid Parent Location. When you edit a Location and attempt to change the Parent Location, the same checks are repeated on any new Parent Location you select (See Creating tab for Criteria).
The following additional checks are also carried out when changing a parent Location at a later time using edit.
