Once you've added images to a product, there isn't a way to delete them in bulk, I'm afraid. However, if you're seeing that you have to delete a bunch of images due to duplicating products, there's a way to prevent this from becoming an issue! When the product duplication dialog box opens up, there's a setting that you can uncheck - this will prevent images from being duplicated along with the rest of the product information:
Hope that's helped! Please feel free to let me know, and you can always give us a call or start a live chat at any time, we're open 24/7 for your convenience and always happy to assist!

Thanks for that tip. While not perfect, I was able to use it to fix several of my client's products.
One tip -- if you use the above you'll probably want to open another window and delete the original product, Then in the duplicated product go to the SEO section and remove the appended -1 from the URL,
Yesterday I was using an app PixPix and told them that we needed the ability to bulk delete from within a product. They said that is an easy add and it would be available by the next day. I woke up this morning and they had answered the call! IT WORKS! No more deleting pics one at a time.
Thank You PixPix you all rock!
Lesson: Never miss the opportunity to ask for what you want! Good Day everyone! #enduser
