After import from Etsy the naming of the images is useless

Hello again!

we imported several hundred products from Etsy a few weeks ago and have now noticed that our images are not being displayed in the google image search due to unusable image titles.

Is there a workflow to edit the image titles in bulk or to automatically link the product URL to the image titles? is there an alternative workaround or is adding an alt text sufficient?

Overall, we wanted to make our work easier by importing from Etsy, but if we now have to upload all the images again, that would be a problem in day-to-day operations.

We look forward to your suggestions for a solution!

Best regards, Paul
