<GuideTitle title="Use public images in Omni content and AI branding" />

Whether you want to update your [agent image](/ai/settings/branding#url-to-agent-image) in the AI Hub or add a photo in a [dashboard Markdown tile](/visualize-present/dashboards/text-markdown), Omni requires a publicly accessible image URL. If you paste in a link that doesn't represent a public image, Omni may fail to load the image.

You can use any host that gives you a direct, public image link. This guide walks through hosting an image on Google Drive and building a link Omni can actually load.

## 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](/ai/settings/branding).

## 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**](/ai/settings/branding#url-to-agent-image) field in AI branding settings
* **Organization theme logo and wordmark** — the [logo and wordmark](/administration/themes/application#branding-assets) 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](https://docs.omni.co/administration/settings/app-policy#external-source-policy).

These fields expect a URL that:

* Points directly at an image file, not a webpage that displays an image
* Is reachable without authentication
* Doesn't expire

For example, a regular Google Drive "share" link (`.../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:

1. Upload the image to Google Drive.

2. Open sharing permissions on the image and set **General access** to **Anyone with the link**.

3. 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 is `1AbCDefGhIJkLmNoPQRstuVWxyz`.

4. Build a link using Drive's thumbnail endpoint:

   ```text theme={null}
   https://drive.google.com/thumbnail?id={fileID}&sz=w640
   ```

   Replace `{fileID}` with the ID from the previous step. `sz=w640` sets the image width in pixels, which you can adjust if you need a different size.

   ```text theme={null}
   https://drive.google.com/thumbnail?id=1AbCDefGhIJkLmNoPQRstuVWxyz&sz=w640
   ```

5. Paste your new `/thumbnail` link into the desired location in Omni. In this example, we'll paste the URL into the [**URL to agent image**](/ai/settings/branding#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](https://imgbb.com) and use the direct link it creates.
