Are you thinking about customizing the product title and description as well?

Thanks for clarifying that! To add text to images in bulk, you can use one of the apps listed here, like Bulk Image Edit ‑ Image SEO. These tools integrate directly with your Shopify admin and not only allow you to add text to the images, but can also help you achieve consistency by resizing images, and can even add details like alt text to improve search engine optimization.
Please keep in mind that if you need help with third-party apps, it's best to reach out to the developer directly. You'll find their contact information on their app listing's page, and can also contact developers for any apps you have installed under Apps > Get support in the admin.
