How do you guys rotate JPEG images from your digital camera so they don't lose quality. I tried ACDSee 4.0, but while the original image was 2 MB, the rotated only like 400 kB, so there must have been a loss in quality. I don't plan on rotating the images in Photoshop and saving them as lossless TIFF, I prefer to keep the original JPEG, just rotated exactly, pixel by pixel. Is that possible?

What you should do is open the JPG through Photoshop.

Image > Rotate Canvas > Rotate it so that its how you want it > then just exit Photoshop, when it prompts you to save changes push yes and it shouldn't give you any trouble about size.

You don't have to exit Photoshop. Just hit File-Save. It will save the rotated image in the same format and file size it originally was.

Paint Shop Pro 9 has a lossless JPEG image rotate.

It should be. Either:

(a) Use Photoshop to rotate the image but do not save the file with File / Save (Ctrl-S), use File / Save As instead and select a lower compression ratio.

File / Save defaults the compression ratio to the one used to open the file originally, but Photoshop's compression engine is probably more efficient than the camera's. Most camera compression engines have to balance speed and quality, while Photoshop's only has to aim for quality. It simply might be operating more efficiently on the file, but by using File / Save As (same file name, overwrite file) you can choose the ratio yourself.

(b) Use Windows XP's file rotate, available on a right-mouse click context menu ONLY when you are in Thumbnails or Filmstrip view mode inside a directory view window (Explorer window). It's rotation seems to keep the file size almost exact - losing only 0.1K during rotation when I just tried it for size modifications a few moments ago.

Irfanview, which is free, also has lossless jpeg rotation.
