AltNinja Alt Text Generator automatically adds or updates the “alt” attribute for images.
It first tries to use the nearest heading on the page (such as H1, H2, H3, etc.) to create relevant alt text. If no suitable heading is found, the plugin can generate alt text using Google’s Gemini AI (via Google AI Studio).
You can configure the plugin in the Settings area and review generated alt text in Media > AltNinja Manager.
<h3>External Services</h3>
This plugin connects to Google’s Gemini API to generate alt text when no heading is available.
What data is sent and when: 
– During AI alt generation (manual run, bulk generate, or on upload if enabled), the plugin sends the image file (base64-encoded) and its MIME type to Google’s endpoint, along with a plain-text prompt and your selected language code if set. 
– Endpoint domain: https://generativelanguage.googleapis.com 
– No WordPress user account data or site URLs are intentionally sent, though images themselves may contain personal information depending on content.
You must create your own API key in Google AI Studio and save it in Settings.
