Automatic generation on upload
When Automatic generation is enabled:
- Every new image upload is added to a processing queue.
- The plugin runs via WP-Cron and:
- Fetches pending images in batches.
- Sends them, plus context, to the IMG Alt Gen service.
- Saves the returned alt text into
_wp_attachment_image_alt.
The plugin never overwrites existing alt text.
Media Library indicators & per-image generation
In Media → Library:
- Each image gets a small status dot:
- Green – Image has alt text.
- Grey – No alt text detected.
- Spinner / pending – Queued or in progress.
- Images show a Generate Alt Text action (for roles with Generate / Partial / Full access):
- Click it to send that single image to the AI.
- The alt text is written back to WordPress when done.
This is ideal for editors who fix images as they go.
Gutenberg editor integration
In the block editor:
- Select an Image block.
- A Generate Alt Text button appears in the block toolbar or sidebar (depending on your editor layout).
- Pressing it:
- Sends only that image, plus the post context, to the AI.
- Updates the alt text field for that image.
This lets authors fix accessibility while they are writing content, without leaving the editor.
Bulk Process Images
The Bulk Process Images page (Partial / Full access only) is designed to clear backlogs:
- Shows a list of images that do not have alt text.
- You can:
- Filter / limit by an optional cap (e.g. “only process 200 images this run”).
- See live token usage as images are processed.
- The plugin runs images in batches to avoid timeouts and respects your batch size and max-images settings.
If you have a large archive, this is the fastest way to get everything up to an accessible baseline.
WooCommerce integration
When WooCommerce integration is enabled:
- Product images automatically include:
- Product title.
- Product attributes (e.g. colour, size).
- Short description where available.
- This gives the AI richer context, which typically produces alt text that:
- Mentions the product name.
- Includes key selling points.
- Remains suitable for screen readers.
SEO plugin integration
IMG Alt Gen integrates with several major SEO plugins, including:
- Yoast SEO
- Rank Math
- All in One SEO (AIOSEO)
- SEOPress
When a supported plugin is active and SEO integration is enabled:
- The focus keyphrase and meta description for the page or post are included in the context sent to the AI.
- This helps align alt text with your SEO strategy while staying readable and accessible.
Output language & filenames as context
Descriptive filenames as context (optional)
There is an option to include descriptive filenames in the AI prompt. This can help when your images are named sensibly (e.g. red-running-shoes.jpg) rather than generic camera names.
Default output language
Configured in Settings – all generated alt text comes back in this language.
