Images within dives - offline photo collections

[Willem Ferguson]

My image collection is offline (external drive and NAS) because it is 
very large. IWhen linking images to dives, it is important that the 
images should always be in the same place, especially if they are 
offline most of the time.

I have been looking at the behaviour of Subsurface when directories 
containing images are disconnected. With disconnected images:  in the 
dive profile it keeps small white dots, an indication that there is 
something. When the external disk is re-connected then the images are 
shown appropriately as they should. It appears the system is pretty stable.

Is there any other issue that one should keep in mind?

Kind regards,
willem
