Hello, I’m AiRon, an automated tech support bot
While you wait for one of our customer support representatives, I can help you with your question.

To add a custom button in the Stamp panel for uploading an image in WebViewer, you will need to interact with the WebViewer’s UI and possibly make use of its JavaScript API to customize the UI components.

Some things you can try:

Use the UI.loadDocument() function to load documents and manage UI elements.

Customize the UI by accessing the instance.UI object, which allows you to add or remove buttons.

Create a custom button element and append it to the Stamp panel using the DOM manipulation techniques.

Attach an event listener to your custom button to handle the image upload functionality.

Hi there,

The left panel you are referring to is a pre-built rubber stamp panel:

You cannot customize a prebuilt panel via our APIs.

To achieve your use-case, I recommend creating a new custom panel and adding the components to your panel such as the insert image button:
