Support for image capture

[Hadryan]

How to get the HTML <img> tag and its different attributes: src, alt, width, ....

[timqian]

It should not be hard to support capturing <img/> tag, but how to display it the sSelected contents part and how to show API caller is a little tricky.

So maybe we display the image in the Selected contents part and add an imgSrc key in the API response?

    {
      "innerText":
      "href":
      "imgSrc":
    }

Do you have better ideas?

Hello everyone, i've created a pull request for this feature, adopting the contract @timqian mentioned above...

But now i'm wondering about other changes in the project architecture we could make... Add tests, define a better contract(i don't think a list of "contents" based on the selectors order is the best approach for an API) etc...

I'll create a new issue to debate those topics :)
