Why I cannot delete original images of products

Hi

All product images are located in:
while the original images are located in:
My client uploads images that are up to 3mb and I would like to remove them to save some web space but if I delete them images from resized folder are not shown on frontend.

So, why is it when I delete original image from "products" folder website doesn't display resized image?

Hello Dama,

The original image from the products folder is required to display images on the front-end side. I think you should upload smaller image instead of uploading a big image up to 3mb.

Sincerely, Giang
