Rotate JPEG (automatically)

Hi everybody,

first, I look for a way to rotate my holiday pictures since some of them are vertical. Is there a way to do this in Photoshop CS without re-saving them and loosing some quality? There are several small programs on the internet that can do this, by just changing the JPEG code without recompression losses. Since everyone says "Photoshop can do everything", I guess it can do this.

Second, I would like to write a script for Photoshop CS that can identify whether a picture is vertically by dividing its width and height and then rotate it if necessary. Afterwards I would like to put this script in an "action" to be able to apply it to a whole directory. Anyone knows Javascript that well? Or has anyone ever written such a script?
Thank you very much!
Nico

1) Use the Irfanview batch function

2) No

Are you sure that using the browser will not resave the picture and lose quality?

How would dividing width by height determine if your image was shot portrait or landscape? You would need some type of mercury switch in your camera that could flag or rotate the image in the camera if the camera was held in the vertical position when then the image was shot.

Picture: 5×10
Landscape: 5/10 = 0.5
Portrait: 10/5 = 2

Yes, but that’s after the original image has already been rotated. The OP want’s to automagically rotate his vertically shot holiday photos that are still in landscape orientation from the camera.

JPEGCROP does all. You can rotate and crop without re-compression of JPEG

and it is free.

What about setting up an action to do it?

Correct me if I’m wrong, but the JPEG format is more or less open.

that everyone knows how one could built such a lossless rotation feature.
So why would Adobe not implement that at least in the newer versions of Photoshop ??? Don’t tell me that you keep your portrait photos in

and slant your head in front of the screen to view the pictures!

Okay, I breathed. And now?

How do you expect a piece of software to do that?
Just the simple fact it has no clue whether to rotate CW or CCW should be enough to realize it cannot be done automatically. Unless someone develops a human eye for Photoshop.

Stop, one moment please. I wasn’t talking about automatic orientation anymore, which no software can do. I was talking about why there is no function for lossless JPEG rotation like in IrfanView, Xnview or others. Just a function like the one offered in JPEGCrop. From all that I’ve read from the answers to this thread, PS simply doesn’t offer a function for this (in my opinion) standard task. Everyone who deals with digital holiday pictures will have to use another software just for rotation? Why does Adobe not implement that?

Because Photoshop isn’t aimed at people who want to rotate their holiday pics, or their Christmas tree pics or anything else that you would consider to be a consumer feature.

What? you mean people are spending hundreds of dollars for this program only to find out it can’t rotate losslessy?
They should demand a refund!!
