So im calling a picture slideshow via API call to play a smb share of pictures - has worked fine for months.
This morning i find an error msg on all the screens around the office - log show it made a meal of opening one or all of the pic files.

Code:

These picture files all open fine within kodi when called on their own.
Any idea what might be causing this - or steps i can take to get a bit more info on the fail?

Any advice much appreciated.
