WD Photo does not publish all my pictures

Is there any possibility that you had (or still have) any zero-byte jpg/jpeg files in any of your large collection of pictures.  I had several zero-byte jpg’s that came of the camera SD card (unknowlingly) and caused the transcoding of the photos in the affected sub-folders to “stall” for days.  After discovering and removing the zero byte files and rebooting the MBL - everything now seems fine.
