Where do I get the API key?
You can create a free key at https://aistudio.google.com/app/apikey. You must also enable the API and billing in your Google Cloud project.
I’m getting an “HTTP 429: Quota Exceeded” error. Why?
This means you have hit your API rate limit (often on free tiers). This plugin includes delays to help prevent this, but if you process a very large number of images or run it frequently, you might still hit a limit. Enabling billing usually provides much higher limits.
How many images does it process at once?
The plugin processes images one at a time with a short delay between each. This prevents server timeouts and respects API rate limits, ensuring a stable experience even on shared hosting.
Will it overwrite existing alt text?
No. The plugin only generates alt text for images that don’t have one.
Is my data sent to the AI service?
Yes. The image file and a text prompt are sent securely to the AI API to generate the description.
