How do I batch resize images with different aspect rations to a certain height, regardless of the width in Photoshop CS6?
I have about 500 images that all have different aspect ratios, and I want to resize them all to be 1,200 pixels tall while maintaining the original aspect ratio of each file. When I try using File – Scripts – Image Processor, and leaving “width” blank, but entering “1200” for height, it says “You must specify width and height when using image resize options for JPEG.”
Is there a way to do this? Thanks!

If you’re on a mac you don’t need photoshop for simple image resizing.
See : processing images with applescriptd.

Sadly, I am not on a Mac, but your answer did give me the idea to just find an image resizing program and do it that way. I guess I just needed to think outside the Photoshop box. Thanks!

I find it easiest to use Photoshop or Bridge in PC or Mac. If you are using PS, drag or copy all your images to one folder first. If you are on Bridge, you can multi-select the images you want to process.
In photoshop: File >> Scripts >> Image Processor
In Bridge: Tools >> Photoshop >> Image Processor
From there, it’s pretty much the same on both except, in Bridge, you would have already selected the files you want to convert and in Photoshop, you can pick an entire folder:
Anyhow, you can tell it to “resize to fit” which means if the image is bigger, it will shrink it (proportionately). So, if you want it to fit into say, 800px width, enter 800px for the width and leave height blank. For web images of my photos, I have it shrink everything to 1200x1200px which means either the height or width (whichever is longest) will be 1200 and the other measurement will be proportionately changed (ie: 4000px by 3000px becomes 1200px by 900px). Hint: if you tell it to put it in the same folder, it creates a JPEG folder and copies the resized images there so you don’t have a lot of clutter. You can also have Image Processor add things like watermarks or perform other actions.

– Create a new action
– while recording resize a picture to your desired height or width (keeping aspect ratio)
– close saving
– stop recording actions
– Use batch process to apply that action to all your pictures…That will apply just one dimension keeping aspect ratio for the other one…
