It is possible to insert image, iframe, another firepad instance into text? about firepad

This isn't currently possible. It's conceivable that firepad could support arbitrary blocks of HTML content embedded in a Firepad, but it's unclear how the UI for that would work. Did you have a specific use case in mind for this?

A collaborative editor for html pages. Basic image/table support. By the way I found widget support in CodeMirror API. It is possible to add table, which occupy the whole line. Or insert widget (image tag) into line after some char. Would it be great to support some of this features?

[mikelehen]

Yeah, that should be possible. The html for the image/table/iframe/whatever wouldn't be collaboratively editable, but it would certainly be possible to embed arbitrary HTML in with a CodeMirror widget.

I'll keep it in mind for a future release.

I've added the ability to create arbitrary "entities" and insert them into Firepad. There's a builtin 'img' entity that can be used as:

firepad.insertEntity('img', { src: 'http://cdn.dashburst.com/wp-content/uploads/2013/01/Grumpy-Cat.jpg', width: 100 })

You can also register your own entities. E.g. see https://github.com/firebase/firepad/blob/448aca7c5148716200645be7d117e74d34b0c668/lib/firepad.js#L520
