How Can I Easily Rotate Images In Finder

I am scanning several thousand slide images, and to save time reframing every slide, I am orienting ALL slides in landscape, regardless of if the image is actually landscape or portrait.


I currently scan 8 images at a time in each batch on an Epson 4990 in full Professional Mode, and then review the scans in Bridge, rotating the images as needed, opening in PSE6 and saving the images in the new orientation. This works fine, but, as I understand it, PSE6 recompresses the images on save, introducing slight degredation to the image.


What I am hoping is that there may be a small utility that can simply change the landscape/portrait property built into the image properties.


I have tried Xee to rotate the image, but it messes up the image, as well as I think it recompresses the image as well.


I don't want to bring the images into iPhoto as they are for a customer, not personal images.


Any help or suggestions on how to rotate an image, without recompressing the image, would be greatly appreciated.


TIA

Why don't you just rotate them in Apples default preview app? Doesn't that have lossless rotation?

This helped me immensely! I had a whole folder (500+) of images that needed rotated (albeit not all of them in the same direction, ha). It was nice to be able to do it in a few seconds with a bit of code. Here's the problem I had, though: The resulting images are between 42-46% larger! Individually it doesn't seem like a huge deal, but it makes the resulting folder huge! Any idea why? I screen-capped the "Get info" box of a before (right) and after (left) pair, see below.

EDIT: By larger I mean file size; The image resolution and dimensions appear unchanged.

You are correct, there was a link much earlier, but there was clearly much discussion after which did not address this very simple step. So I spelled it out sp it might be more obvious.


However, I do not believe is requires Graphic Converter. The previous link makes no reference to that. If you have some information about this, please fill me in!
