How do I overwrite images with the same name??

[pjr710]

Guys, I have 15k products. I get my images from a central source, sometimes these images are updated but they keep the same image name.

How can I upload and "overwrite" my existing images on my magento store?

I tried Add/Update, but it seems to only add new that never existed, it doesn't overwrite existing images.

DELETE i'm pretty sure just deletes the product

and REPLACE i thought would replace just the image, but I didn't try it. I assume it will be creating an entirely new product and require all the extra data.

Literally all I am trying to do is change "image_1.jpg" on my server with a new "image_1.jpg" from my import folder.

Please help!

Thank you

Importing and "Replacing Existing Complex Data" is probably the option that you want. However, I would recommend testing this in a staging or development environment on first attempt. 

Some documentation is provided on this functionality: http://docs.magento.com/m2/ce/user_guide/system/data-import.html
