 > It is probably possible to write a plugin that does that.  For example,
 you could use the `image_resize_dimensions` filter to skip any images that
 are similar in size to images already generated.

 think are necessary.  There are existing plugins which can do that, e.g.,
 [https://wordpress.org/plugins/disable-media-sizes/ Disable Media Sizes].


 What WordPress does with the images isn’t really documented and happens in
 the background.
 You can only see the generated files if you look in the uploads folder via
 FTP.
 Now that I understand what’s going on, I can pay attention to this when
 uploading images.
 I prefer not to change the default settings, because they must serve a
 purpose and other parts of the code expect these sizes.
 In the future, I will use specific sizes and aspect ratios for my images.
 I’ve summarized what to look out for in my blog and addressed it to
 German-speaking Darktable users.
