@dosubot[bot] commented on GitHub (Jun 12, 2025):

Dify 1.4.1 supports displaying images in chatflow outputs using Markdown image syntax, like ![alt text](image_url). The backend serializes image references as Markdown, and the frontend renders them using a custom Markdown component that supports images via an Img block and ImageGallery for preview and usability. There is no support for raw HTML <img> tags or other HTML elements—certain HTML tags are explicitly disallowed in the renderer, so Markdown is the recommended approach for images. If your images are not displaying, make sure the image URLs are valid and accessible, and that you are using the correct Markdown syntax for images.
