Quick answers

Frequently asked questions.

Why does it ask what the page is about?
The same photo needs different alt text on different pages. On a recipe page a photo of soup is about the dish; on a page selling bowls it is about the bowl.
Which images can I use?
JPG, PNG, WebP and GIF up to 10 MB. Uploads are resized in your browser before they are sent.
Is my image stored?
No. It is sent to our AI model provider to write the alt text and is not saved by Realword.
