How to batch resize in Bridge CS6 or Image Processor using height only?

Question

I have batches of images that need to resized based on height only and would like to do so using Bridge/Image Processor. My height requirement is 1140px, however the original images are varied in landscape/portrait orientation and are of different aspect ratios (2:3, 3:4, etc). So far what I have had to do is filter in Bridge just the landscape images then select an aspect ratio, then plug into Image Processor the exact pixel dimensions of the resized images (that I discovered using Photoshop to resize and check the resulting pixel dimension). There has to be a more efficient way.
An example of what I am running into:
Image 1
Original file = 5616 h x 3744 w Portrait orientation
Resized file = 1140 h x 760 w
Image 2
Original file = 3744 h x 5616 w Landscape
Resized file = 1140 h x 1710 w
Image 3
Original file = 4652 h x 3489 w Portrait
Resized file = 1140 h x 855 w
From that example, is there a way I can plug just the height number in Image Processor (or any other Photoshop utility) so I can just batch out a bunch of images all at once?
FYI - I am not interested in buying any new software such as Lightroom to accomplish this task. I would like to remain within Photoshop/Bridge if possible.

You can do what you want with Image Processor without a script.  All you have to do is enter the number of pixels you want for the height (1140 pixels in your case) and then enter a number for the width that is wider than any image you will process.  Image processor will always resize the images to fit inside this rectangle.  That is, the height will always be 1140 and the width will fall where it may.  It works like the Fit Image command in Photoshop.
