Product Image Alt Text

The Magento extension runs in the background whenever you add or update a product in your catalog. It will look for any images that are missing alt text, and generate alt text for those images using your product data. Product images with existing alt text are skipped by default.

Alt text is generated as part of Magento's background cron jobs, so don't worry if you don't see it immediately. Typically these jobs run at least once per day, but your store may be configured differently.

Manually Running Alt Text Generation

The extension runs alt text jobs using Magento's built-in queuing system. If you need to immediately process these background jobs for alt text generation, you can run the following magento command:

bin/magento queue:consumers:start AlttextAiProductUpdate --max-messages=1

(set the value of max-messages to however many jobs you need to process, or leave off that argument to process all jobs and wait for new ones)

Controlling Alt Text for Product Images

Use the extension Configuration page (Stores: Configuration: Services: to control which products are processed for alt text, along with other features. You can skip products which are not active and/or published in your online store, as well as control how products with multiple images are handled.
