FAQ

Do I need API keys for all providers?

No! The plugin currently supports 3 providers: OpenAI GPT-4 Vision, Google Cloud Vision, and Cloudmersive. You can use any combination. Start with Cloudmersive (free 800 calls/month) and add others as needed. Azure and AWS providers are planned for future releases.

How does the intelligent fallback work?

The plugin tries providers in order of priority. If one fails (API error, rate limit, etc.), it automatically tries the next available provider. This ensures reliable alt text generation.

Can I control costs?

Yes! The React dashboard provides real-time cost tracking, usage statistics, and spending alerts. You can set monthly limits and choose cost-effective providers for different image types.

How accurate is the generated alt text?

The plugin uses advanced quality scoring to evaluate alt text descriptiveness, length, and relevance. Multiple AI providers ensure high accuracy, and you can always manually edit generated text.

Will this work with my theme/page builder?

Yes! The plugin works with any theme or page builder because it stores alt text in WordPress’s standard image metadata fields. It’s compatible with Gutenberg, Classic Editor, Elementor, Divi, and others.

What image formats are supported?

All standard web formats: JPEG, PNG, GIF, WebP, and other WordPress-supported formats. The plugin automatically validates image compatibility before processing.

How does bulk processing work?

Bulk processing uses WordPress’s background scheduling system to process images at 1 per second (respecting API rate limits). You can filter by date ranges and track progress in real-time.

Can I customize the alt text style?

Yes! Each provider offers customization options for tone, length, and detail level. The React interface provides easy configuration for each provider’s specific parameters.

Is my data secure?

Yes! API keys are securely stored using WordPress standards. Images are only sent to providers you’ve configured, and no images are permanently stored by external services.
