All social and SEO plugins – except one that I know of – use the full size image URL from the WordPress media library when adding image meta tags to the webpage (ie.
twitter:image, etc.), and/or adding images to Schema JSON-LD markup for the webpage. This can be problematic for several reasons…
- The image resolution may be too small.
- The image resolution may be too large and the file size too big.
- The aspect ratio (width or height) may exceed a maximum value.
- The image displayed on the social / search site is center cropped.
