Ever had the problem of pictures taken in portrait showing up in landscape in your emails, on your blog or on your mobile device? JPEG-EXIF autorotate is the solution. It’s quick, it’s simple, it’s free.
No, I will not try and explain the technical details. Olli Savolainen does that a lot better than me.
Thank you Olli, I use it for autorotating photos taken with my iPhone 4.
