I moved my pictures from my phone storage to my SD card, but I must've goofed up because I have no thumbnail images on my SD card. Coincidentally, I do have thumbnails on my phone storage even though the pictures are now moved. I tried copying the thumbnail folder and images from phone to SD, but I still don't see thumbnail images when browsing pictures files on my SD card.
How can I restore or create thumbnail images on my SD pictures?
Thanks in advance!
