: How can I create an action to increase my canvas size in Photoshop ONLY if the canvas is X? For starters to be clear, I'm looking to manipulate canvas size. Not image size. I want to create

Photoshop Actions (what we used to call "Macros," back in the day) are just recorded steps. There is no equivalent of conditional statements, loops, or any of the things you'd find in a scripting language.

As horatio says, this is absolutely doable with scripting. You'll find a complete manual for each of the three possible scripting languages (Applescript for the Mac, VBscript for Windows, javascript for either) in your Photoshop application folder. Look in the Photoshop [version #] folder for one called "Scripting" and inside that a folder called "Documents."

If you utilize the Script Events Manager (it's under File > Scripts), you can run your script any time a file is opened. It shouldn't be a complex script, since all you're doing is putting a canvas resize inside a simple conditional. The good folks on SO might help you out with it, or you'll find a small army of Photoshop scripting mavens on the Adobe website. Scripters, in my experience, are incredibly helpful people, and will usually write a script, test it, and stick it in an answer for you.
