I'm trying to find a program that allows me to batch rotate a bunch of images losslessly. So far, I'm using IrFanView's built-in lossless jpeg transformation plugin to do this, but I can only do 1 pic by 1 pic. That's very tedious, esp. after a photoshoot where I may need to rotate like 50 pics!!
Anyone has any good/simple programs that allows me to do this kind of rotation? Thanks! (Please recommend only lossless rotation algos!!)
