  2. Compress Your Image:

    Reduce image sizes by up to 90% through image compression techniques (Lossy, Lossless, and glossy) and therefore increase page loading speed. For example, there are tools like ShortPixel image compression which might help with the said process.

  3. Resize Your Image:

    Optimize image size by adhering to recommended dimensions for various image types (featured image, portrait image, background images, etc.), reducing loading times and resource consumption

  4. Use Faster-loading Image Formats: WebP or GIF:

    Use WebP or GIF as faster loading images. For instance, WebP, efficiently compresses images, leading to lower file sizes but maintaining quality.

  5. Use a Content Driven Network (CDN):

    Use a CDN like Optimole, Bunny, or Cloudflare Images which is able to optimize pictures in realtime through compression, resizing and caching thus enhancing mobile page loading time.

  6. Use Lazy Loading Images:

    Load only necessary content first, and delay other loads when users start scrolling (lazy load). Use lazy load plugins such as Smush or Optimole for WordPress to optimize mobile speed.

  7. Use Caching:

    Use image caching plugins such as W3 Total Cache, WP Super Cache, or WP Fastest Cache to make images accessible on a faster location to users to prevent a reload of images thus enhancing your page performance.

  8. Store and Use Images From External Servers:

    Improve image delivery by caching images from external servers, particularly ones offered by CDNs or image holding services.

  9. Use Mobile-Friendly Theme (AMP Enabled):

    Select an AMP-enabled mobile-friendly theme from Google. It enables fast loading of images on mobile devices while also gives the option of optimal image sizes for various devices.
