For the full reference on the media library, see Brand Wiki. This page just follows the video.
Images live in Brand Wiki, not the email builder
The email template editor only takes an image URL — it has no upload button of its own. Images and video for your company live in one shared library instead: Media Studio, inside Brand Wiki.1
Open Media Studio
Open the marketing suite, go to Brand Wiki, then the Media Studio tab.
2
Add your image
Drop your file (JPG, PNG, WEBP, GIF, SVG, HEIC, AVIF, BMP, TIFF, up to 25 MB), or use AI Generate with a prompt, an aspect ratio, and a style to create one instead.
3
Copy the asset URL
Hover the image in the library grid and click Copy to copy its URL.
4
Paste it into your template
Back in the email template editor, paste that URL into the Hero Image field in the properties panel, or into an Image content block.
Anyone with workspace access can upload to the media library or generate images there, even without an administrator or marketing manager role. Deleting an item from the library is permanent and has no confirmation dialog.
