Sometimes when I rotate a photo it doesn rotate, whats wrong?
When your computer downloads an image, it stores it in a cache so that it doesn’t have to download it again. If you ever rotate an image and find that it doesn’t do anything, it’s most likely because your computer is just using this cached photo instead of downloading the new, rotated photo. To fix this, hold the CTRL key and click the Refresh button of your browser, this will force your computer to re-download the photo again and you should find that it is rotated.
