On my Mini 2 I import photos using the Apple SD card reader so I can preview them, do some editing, and email them. Before when I would insert the card, the import screen would pop up and it would show me a thumbnail of the images so I could select exactly which ones I wanted. I tried importing some photos last night, but instead of showing the thumbnails it shows a gray box with the text 'jpg' in the middle of it. I've tried looking through settings to see if something changed, I've restarted, etc.... with no luck. Anyone else having similar issues?
