sorry, I don't have this Problem because I move my Photo to another Folder on SdCard in short periods
In iGO I have an extra Folder on SdCard for special Camper pictures, the white iGO

and SYS.txt
[poi]
picturepoi_has_mypicturepoi=1
picturepoi_folder="/storage/Card-Name/my_Camper-jpg"
picturepoi_scan="/storage/Card-Name/my_Camper-jpg"
