Create screenshots of URLs.

Depends on some infrastructure for saving/serving screenshots, needs to be discussed first. First simple proposal:

• save the file in a defined directory, filename is a generated UUID
• a URL-prefix is defined in the parameters
• screenshot_url is prefix + filename

Candidate for a screenshot module: python-webkit2png, not good maintained, thus requires a fork of it to merge all open PRs from there.

What do you think of using headless chrome for it? I dont like the dependency on chrome though. However it will be much better solution.

We can't avoid a dependency. We can also have multiple supported browsers if that is necessary.

An argument for chrome/chromium is, that it is widespread - and the rendering shouldn't have surprises.

We will need this for 3.0

In the last IHAP meeting lookyloo was mentioned as possible screenshotting service, although slow.
