Requirements
- A Google account you can upload the image to. This guide includes Google-specific instructions, but you can use a different host if you prefer.
- Organization Admin permissions in Omni, if updating AI branding settings.
Why this happens
Several places in Omni ask for the URL of a publicly hosted image:- AI Hub agent image — the URL to agent image field in AI branding settings
- Organization theme logo and wordmark — the logo and wordmark fields in application theme settings
- Omni app images - Omni accepts image hosts when building an app, but the image’s host must be added to the app’s External source policy.
- Points directly at an image file, not a webpage that displays an image
- Is reachable without authentication
- Doesn’t expire
.../file/d/{fileID}/view) opens a preview page rather than the raw image, so Omni can’t load it.
How to fix it
You can use any host that gives you a public image link, but this example uses Google Drive:- Upload the image to Google Drive.
- Open sharing permissions on the image and set General access to Anyone with the link.
-
Copy the share link and extract the file ID. In a link like
https://drive.google.com/file/d/1AbCDefGhIJkLmNoPQRstuVWxyz/view?usp=sharing, the file ID is the segment between/d/and/view. In this example, the file ID is1AbCDefGhIJkLmNoPQRstuVWxyz. -
Build a link using Drive’s thumbnail endpoint:
Replace
{fileID}with the ID from the previous step.sz=w640sets the image width in pixels, which you can adjust if you need a different size. -
Paste your new
/thumbnaillink into the desired location in Omni. In this example, we’ll paste the URL into the URL to agent image field in AI Hub > General > Branding. Omni recommends a square PNG, 128x128 pixels, for best results.
Alternative hosting providers
If you’d rather not use Google Drive, any service that returns a stable, public image URL will work. For example, you can upload an image to imgbb.com and use the direct link it creates.Next steps
