DW Extension Hide or Substitute Broken Image
Things happen -images can be accidentally moved or deleted from the server. Sometimes you can not be 100% sure the image exists, for example when loading the source attribute for the images from a database (especially if you are taking over a project previously managed by someone else).
This Behavior solves the problem in the following way:
Once the page is loaded it will check for missing images and either hide broken image icons or display a substitute image for all those that are missing.
Access this behavior from 'Linecraft' menu 'Hide or Substitute Broken Image' menu inside Behaviors panel.
