Tool needed: Merge images into 1

Hello, I am hoping someone knows a tool, or has a creative solution to the challenge I am facing:

  • I want to generate a new image, by combining multiple images side by side.

Each individual image is 1 character, so with multiple images I can create words. For example:
To make the word ‘ZACH’, I need to combine 4 images (Z, A, C, H).

I have the images of all the characters available. I am looking for a tool to generate these images automatically, via Make.
That way I can enter a new word in a Google Sheet, have the image generated via Make and then create a new product page in WooCommerce for that word.

I haven’t found a way to do this in Make yet. Do you guys know of a tool to get this done that can be used with Make? Thanks in advance!
