1. can i only use the tool to create alt texts or can i also add some myself?

2. can i use it to select existing/new products/photos and change them to bulk with my own texts? And ideally via a search, i.e. with just a few clicks, without uploading all the images or similar?

(example: I am looking for product X with 7 photos. Can I click on the product and then either have 7 alt texts created for me or add 7 alt texts myself?

3. do the credits only count for images created with AI or also those where I have added the text myself?

I'm basically interested in whether the images have to be uploaded every time or whether I have direct access to the products with the photos with the tool and can then create the alt texts with AI or myself with a single click.

Thank you!
