Equal borders for non square images of different sizes.
Hello, I need to create a border on many (over a thousand) images of different pixel sizes. Most of the images are not square. The borders need to appear relatively proportional regardless of how big or small the image size is. Using an action that increases (relative) canvas size by percentage creates borders of the same proportion, but on images that are not square, the x and y borders are different sizes. (insert sad face here). Is there a way to do this in photoshop I am not aware of that works on non square images? There is an old post on this forum that asks this question, (https://community.adobe.com/t5/photoshop-ecosystem-discussions/need-action-that-makes-an-equal-sized-border-for-images-with-different-sizes/td-p/11876979) and (https://community.adobe.com/t5/photoshop-ecosystem-discussions/action-that-uses-a-percentage-of-image-size-in-pixel-dimensions/m-p/9897687#M174298) but the answers involve scripting and honestly I did not understand... Thank you in advance.
