# Full-page screenshots with sticky headers and lazy images fixed

**Use case:** 

Full-page PNG screenshots that come out clean on modern sites: the page is scrolled first so lazy-loaded images render, then scrolled back to the top, and sticky or fixed headers and cookie bars are shown once instead of repeating down the image or landing in the middle of it. One dataset row per page links to the image. Pay per event: $0.004 per screenshot captured.

## About this Actor

This example demonstrates how to use [Website Screenshot & Visual Regression Diff](https://apify.com/lintlab/screenshot-diff.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/lintlab/screenshot-diff.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/lintlab/screenshot-diff.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
