Is there a need for blog featured image to tap into the Settings > Media Settings and create different sizes
Seeing as it’s only used in one place (the top of the blog post) what if I disable all the media settings image sizes before uploading a featured image, then I only have the image I uploaded. For a neat wp-content/uploads folder.
To obtain the right size I will follow other recommendations see here and find my exact container width and size the featured image precisely before uploading.
Or are the other images sizes needed for phone layouts etc to be responsive. Still don’t quite understand what is responsive and what it requires
thanks
