常見問題集
-
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.
