Programming as Theory Building

Peter Naur

Peter Naur's classic 1985 essay "Programming as Theory Building" argues that a program is not its source code. A program is a shared mental construct (he uses the word theory) that lives in the minds of the people who work on it. If you lose the people, you lose the program. The code is merely a written representation of the program, and it's lossy, so you can't reconstruct

What to do

Use the alt text to associate the additional images - besides the variant image - to the option value. Example: say you have 3 images that show the Blue variants, then a) associate the first image as variant image to all Blue variants, and b) set the alt text of the 2 additional images to 'Blue'.
Copy+paste the code found in the product.liquid snippet below at the bottom of your product.liquid template.

How that works, essentially

Only the images associated to the currently selected variant are shown. Other images are hidden.
