How to edit multiple photos at once?

So I want software that auto rotates and auto crops.

I think you can do it with Irfanview, but I’m not 100% sure. It’s a terrific and better yet, free photo viewing and editing program for Windows. You can do a lot a batch processing with it but it’s only available for Windows and I’m on my Mac now so I can’t load it up and tell you for sure if it will do what you want. But it’s free and a very quick download so you could at least check it out and see if it will do what you want done. I usually transfer my images to my laptop which is a window machine just so I can use Irfanview because there’s nothing like it for the Mac. I use it a lot to do batch resizing to turn the 1.3 mb image files into smaller files so they’re more convenient and easier to email. If you work with a lot of photos and images it’s a really good piece of software to have around anyway. Check it out.

Edit: Here’s and article/instructions on how to do batch processing in Irfanview and it looks like you can do batch rotating and cropping. I’ve just never used it for that.

If you really have thousands of images, you might want to invest in Adobe Photoshop Elements. It will allow you to create an action, that you can apply to individaul images or folders of images. Simply put, make changes to one image, and apply the same change to folders of images with one mouse click. The time saved will more than make up for the $70. Plus you’ll have a really nice piece of software that will allow you do do a whole lot more than just crop and rotate.

the full adobe photoshop suite has a component called bridge. That’s useful for organizing and tagging photos and among other things will let you perform the same operation on many photos at once (it actually does them one at a time, or one at a time per CPU, but you give it one command to do the whole bunch). The less expensive but very capable adobe lightroom also has some capability to do the same thing to groups of photos like turn all the sideways ones 90 degree to the right…

batch process, most photo editing program can do that, such as photoshop, photostudio and so forth, I personally use photostudio, works great for me, you may find some info here: http://www.arcsoft.com/photostudio/
