Plugin Description: Meta Injector

What This Plugin Does:

1. Automatically adds the max-image-preview:large directive to the "robots" meta tag:

   • This directive enables search engines (Google, Bing, Yahoo, Yandex) to display larger images in content previews, improving the site's visibility in search results.

2. Checks for the existence of an existing "robots" tag:

   • If the tag already contains the noindex directive, the plugin makes no changes, respecting the existing configuration.
   • If the "robots" tag exists with other directives (e.g., index, follow), the plugin simply appends the max-image-preview:large directive without overwriting the current settings.

3. Automatically creates a "robots" meta tag if none exists:

   • If a page lacks a "robots" meta tag, the plugin adds one with the default configuration: index, follow, max-image-preview:large.

Benefits:

• SEO-Friendly: Improves the visibility of site images in search engines (Google, Bing, Yahoo, Yandex), driving clicks and engagement.
• Seamless Configuration: Works automatically without requiring additional setup.
• Respects Existing Settings: Preserves manually configured or plugin-added directives, ensuring compatibility.

How It Works:

• The plugin activates on all Joomla pages before the head section is rendered (onBeforeCompileHead).
• It ensures only HTML documents are affected.
• Depending on the current configuration, it updates or adds the "robots" meta tag.

Compatibility:

• Joomla Version: Compatible with Joomla 4 and 5, or other formats.
