Hello

When I add a featured image to a product (50ko, all my images are optimized before upload with iloveimg.com)

I noticed that 9 others versions are created in uploads folder : 

image-name-100x100.png : 6 ko

image-name-150x150.png : 12 ko

image-name-300x300.png : 34 ko

image-name-600x600.png : 94 ko

image-name-768x768.png : 204 ko

image-name-788x788.png : 236 ko

image-name-1024x1024.png : 125 ko

image-name-1536x1536.png : 397 ko

image-name-2048x2048.png : 158 ko

+ 4 images files in thumbs_dir (9 ko, 2 ko, 8 ko, 2 ko)

1) It create lots of files, and my server is limited to 1 million files (even if it still has empty space)

2) many of these files are not used in frontend

3) new images are not optimized and are bigger than the original

Is there a way to fix this ? Have less new image created by the theme and have them optimized ?

If it can help in Rehub options I have

Equal eight grid layout for blog / category / search

big post offer for post layout

width style is 1200 px

woo archive is directory grid

product layout is directory style

Disable resize for Featured images is OFF

Enable lazyload script on thumbnails is ON

In WordPress Images Options I made no change and got 150 / 300 / 1024

thank you
