For mobile and tablet, the WordPress theme should be smart enough to automatically generate smaller versions of the images depending on the device size. As for any other images on the site not full-screen images , a table is not possible because image sizes depend on the site design.
But another site might have the blog at px wide, so all that changes. Wix does indeed recommend uploading high-res images , which the platform them automatically compresses and resized depending on the template needs. If the image is used in a large slideshow, Wix generated a larger JPG image.
If used as a thumbnail, a smaller-sized JPG is generated. But… people can still get access to the high-res images if they know how to tweak the URLs of those images.

The content of the text-only pages shall be updated whenever the primary page changes. This helps us to focus on the desktop version for web-search. When users visit that desktop version with a smartphone, you can redirect them to the mobile version. Even better however is to use the same URLs and to show the appropriate version of the content without a redirect John Mueller, Google.
