i found my images and set a purple colour label to distinguish my joiner from the rest of my image. then i edited 1 image and synced the rest so that the whole joiner will have the same edits.

I put my images into the file automate photo merge then I put my images into the photo merge which

under file automate photo merge then I put my my images into this section then the computer

I then reedited my image to be black and white and resynchronized the images to re do it and create the same image but in black and white.

this is the end product of the black and white joiner i have created.
