I am currently loading a lot of photos (JPEG files) into Moments on my NAS (DS220+). Sometimes the files will load and sometimes I just get a red "Fail" message. Once it goes into "Fail" mode it seems to always fail and then for no explicable reason it decides to start loading. I can reliably load the files if I first open in a PDF reader (I'm using Preview) and drag them into Moments. But that is very tedious. Any suggestions? These files are vintage early 2000s. Has the PDF implementation changed? Thanks!
