Canvas is a WordPress plugin which allows users to perform basic editing functionalities on images by utilizing basic drawing tools like pencil, pen, eraser, color picker etc.
After adding this plugin to WordPress, it will create two pages dynamically on your website: a canvas page and gallery page. In the gallery page, users can view drawings by other users. Users can print images on a page and can also send via email to anyone.
A captcha is added to the “send image” form to avoid spam.
