Replace product image in bulk

[heldercervantes]

Hi.

 

I have a list of products where I need to change the photo. It's the same photo for every product, but it's around 1800 of them.

 

This is NOT a generic placeholder. All these products belong to a number of categories that share the same image.

 

I tried importing CSV and feeding a file containing column with the IDs and the second one repeating the path to the photo. But this is not replacing the photos for products that already have them, so I ended up with a job partially done.

 

Can anyone help out with a snippet for iterating through a list of product IDs and removing all images from each one?

Hi

 

There is a column in the upload CSV file to delete existing images (see screen shot) set this to yes when importing new images. 

 

I have a great "CSV Product Upload" how to video here: 

 

 

Hope this helps..

Thank you for your help. Maybe if I kept my eyes open I wouldn't have needed to ask

 

Turns out I also had a problem with the update dates that caused a lot of products not to be affected. I found a solution for that one here:
