All my products are Simple products with one image. I need to make a make a change to all the images and replace them all. The images will all be the same size and have the same names.
How can I replace all the images all at once?
Using the latest version of M2 btw.
Maybe the easiest way is to use the Import feature to update existing products.
You can't update the image attribute with Mass Actions.
For anyone who is interested, I replaced them all by uploading the new images to their storage directory:
From there they are organized by their names, first letter then second letter. Overwriting the images there then flushing the images cache updated all the images...
