Image size Regenration Issue

hi,
i used a plugin that prevents image size regeneration on upload
so i prevented the regenration of all sizes so i can reduce the number of files on my site
however, i lost many product pics because of that and i don’t the main cause
then as i sent you in the picture below, when i hover over a product i get that kind of display
how can i fix it
i also sent a pic for the image regenration sizes that i prevented, please take a look and let me know if there’s sizes that are necessary for the theme and can’t be included in the regenration prevention?
Thanks
