Lets commenters add a drawing or doodle on a picture from a given post.
DrawBlog lets those who comment on your blog add a quick drawing to accompany their comment. They can select colors or pen widths, then use the mouse to doodle a picture on a small canvas.
Additionally, they can choose an image from your blog post and copy it to the canvas, and doodle on top of it.
The height and width of the canvas is editable in the admin settings, as is some of the wording for the plugin (like the link that toggles the canvas on and off).
If users choose, they can uncheck the box that says "Include this drawing with my comment", and the picture won't be saved when they submit their comment.
NOTE: DrawBlog is not yet compatible with Jetpack's comments module, nor with Disqus. Workin' on it.
