Photos show up as blank after putting them on SD card Inserted a 32 GB Micro SD card. Phone recognizes it and I can copy photos on to it and they all appear to be there. 

But when I restart the phone many of the photos show up blank. Any way to fix this?  I tried another card with similar results.

My phone runs Android 4.4.
Try erasing the photo gallery application data and reboot before starting the app again, so that it has to load again thumbnails and image locations once more when it starts. Perhaps it is not updating propper data.
