I have a grouped with some associated products. When the image on the grouped is updated, I'd like to save the same image on the associated products also.
I tried with the "catalog_product_gallery_upload_image_after" observer: this observer gets trigged on image change but it doesn't give me any info on the product that has been saved.
I also tried with the more generic "product_save" event (after and before): here I have the product data but I cannot fetch the image change.
Is there a way to trigger my code on the image change in a way that I can intercept the image change with the data of the product that has been saved?
