I tried rotating one of my son's pic's using Google's Picasa2 today. Guess what!? It doesn't really rotate the actual JPEG file, instead it memorizes the operation internally.
In other words, things will look and act as they should, but! as long as you are using Picasa. Have you, by any chance, want to view your file by using standard Windows image viewer, you are in for a surprise, the pic remains unchanged!
Turns out, there is a way around this: just click Ctrl-S to "save the changed image" in picasa.
Still...was enough to piss me off!

True, true... Even the best tools ever may piss you off a whole lot when you don't look over the manual first. Who would ever think you need to press Ctrl+S to save changes....
And there are other crazy people -- control freaks, who do not want anything changes in the precious jpeg until they say so. Rotation, being a resampling, is just a killer for them.
I guess you just can’t make everyone happy at the default setting.
Yes, but the dude is right
Yes, but the dude is right in a sense that they didn't provide an alternative option! Plus, if you rotate 90 or 180 degrees it is lossless, so no harm is done to the original image.
