For the last couple weeks I've had a recurring issue that I can't seem to figure out. I have a couple hundred photos on my SD card, all of them work flawlessly. Except, the latest pictures I take don't seem to be readable. I take a pic, review it, upload, do whatever I want. Then I close it, close the application. Then go in to gallery, and the file is unreadable. If I use a file manager, it reads the picture just fine, but HTC's gallery won't render the preview. Any idea why??
