Drawing Tool in WebForm Drupal 6 website.

I need to embed a drawing tool into a webform to allow a visitor to sketch a diagram and have it sent as an attachment to the email from the WebForm.

Been looking around but have not found a solution for Drupal 6.

Any ideas?
Image Editor will do that, 

Drupal 6 version allows to edit Imagefield items and save them back either by replacing the original image or adding new Imagefield item. but I'm not sure it will integrate with webform, You need to test it.
