[Dummy] Update Docs

[padmkris123]

Based on our conversation about adding images in Adobe Express Add-ons, here's a comprehensive guide on using the Image APIs:

Key Features

1. Basic Image Import: Use addImage() method from addOnUISdk.app.document to add images
2. Multiple Sources: Support for both remote and local image sources
3. Animated Images: Special support for animated GIFs via addAnimatedImage()
4. Media Attributes: Optional configuration for image properties

Example Code

import { addOnUISdk } from "https://new.express.adobe.com/static/add-on-sdk/sdk.js";

// Example: Adding an image from a URL
const imageUrl = "https://example.com/image.jpg";
const response = await fetch(imageUrl);
const blob = await response.blob();
await addOnUISdk.app.document.addImage(blob);

// Example: Adding an animated GIF
const gifUrl = "https://example.com/animation.gif";
const gifResponse = await fetch(gifUrl);
const gifBlob = await gifResponse.blob();
await addOnUISdk.app.document.addAnimatedImage(gifBlob);

Important Notes

1. Images must be provided as Blob objects
2. Supported formats include PNG, JPEG, and GIF
3. Error handling is recommended for network requests
4. Consider image size and format limitations
5. Use MediaAttributes for advanced configuration
