详情介绍:

Presswell Alt Text Generator helps teams reduce accessibility backlog by generating descriptive alt text for new and existing images. Connect a provider, choose a model, and run generation workflows directly inside wp-admin. Features

Supports OpenAI, Anthropic Claude, and Google Gemini multimodal models
Generates alt text for individual images in the Media Library and media modal
Processes missing-alt backlogs in batches with a dedicated bulk queue
Handles provider rate limits with automatic cooldown locks
Adds a Media Library column with quick generate/regenerate actions
Provides a customizable prompt seed for output consistency

Media Library Tools Inline actions let you generate or regenerate alt text directly from each image row. When an image has no alt text, the column displays a "Generate Alt Text" link that triggers the AJAX workflow and replaces itself with the result. Bulk Generator The Bulk page counts images missing alt text, allows regeneration preferences, and runs batches while surfacing progress, failures, and rate-limit pauses. Documentation Filters

pwatg_available_services — Modify the available AI providers
pwatg_available_models — Modify the available models for each provider
pwatg_provider_registry — Map provider slugs to custom service classes

WP-CLI If WP-CLI is available, you can run single-image generation, bulk generation, and missing-alt counts from the command line:

wp pwatg generate <attachment-id>
wp pwatg bulk-generate
wp pwatg count-missing
wp pwatg network-bulk-generate

Optional CLI flags:

wp pwatg generate <attachment-id> --force
wp pwatg bulk-generate --force
wp pwatg bulk-generate --limit=<int>
wp pwatg bulk-generate --missing-only
wp pwatg network-bulk-generate --force
wp pwatg network-bulk-generate --limit=<int>
wp pwatg network-bulk-generate --missing-only
wp pwatg network-bulk-generate --sites=<id,id,...>

安装:

Install via the WordPress plugin installer, or manually upload the plugin directory to wp-content/plugins/. Configuration

Activate the plugin.
Visit Settings -> Alt Text Generator to enter your API key and choose a model.
(Optional) Enable auto-generate-on-upload if you want every new image to receive alt text automatically.
Use the Bulk tool under Media -> Alt Text Bulk Generator or inline Media Library actions.

常见问题:

Which providers are supported?

OpenAI (GPT-4.1, GPT-4o), Anthropic Claude (3.5 Haiku/Sonnet, 3 Opus), and Google Gemini (2.0 Flash, 1.5 Flash/Pro). You can extend the provider registry to add more.

Where are API keys stored?

Keys are stored in the site options table. They are used only when calling the selected provider from your server.

Can I regenerate specific images without affecting others?

Yes. Use the inline "Regenerate Alt Text" link in the Media Library or media modal to update a single attachment without affecting the rest of the queue, or run wp pwatg generate <attachment-id> --force.

Can I run generation from WP-CLI?

Yes. Use wp pwatg generate <attachment-id> for one image, wp pwatg bulk-generate for a batch run, and wp pwatg count-missing to check remaining backlog.

Can I run bulk generation network-wide on Multisite?

Yes. Use wp pwatg network-bulk-generate to process all sites in the network, or pass --sites=<id,id,...> to target specific site IDs.

How does rate limiting work?

If a provider responds with a retry-after header, the plugin sets a transient lock and pauses both single and bulk runs until the cooldown expires.
