I am using atelier theme on a shop website and I have seen the disk space grow rapidly. In my analysis, I have noticed that Atelier is creating 17 different media sizes when it uploads an image:
thumbnail - 150x150 medium - 300x300 medium_large - 768x9999 large - 1024x1024 shop_thumbnail - 180x180 shop_catalog - 800x800 shop_single - 600x600 post-thumbnail - 220x150 widget-image - 94x70 thumb-square - 250x250 thumb-image - 600x450 thumb-image-twocol - 900x675 thumb-image-onecol - 1800x1200 blog-image - 1280x9999 gallery-image - 1000x9999 large-square - 1200x1200 full-width-image-gallery - 1280x720
This seems to be a little bit of overkill to me especially when uploading a batch of images sometimes results in memory overload = Error 500.
Not only is it now consuming GBs of space but there are 1000's and 1000's of files...
What happens if I do remove some of these media sizes? Will the website lose reference and display an missing image OR will it simple use an alternate size?
And also, is there a simple way to unlink and delete all the additional images size I no longer want?
