accessing to image in eclipse plugin

Question

I'm trying to set the background image of canvas using

canvas.setBackgroundImage(image);

How can i set the image with a *.png file that is stored in plugin's image sub-directory ?

Something like this:

PlatformUI.getWorkbench().getSharedImages().getImage(ISharedImages.IMG_OBJS_INFO_TSK)

but I want to use my image file instead of the shared image.

For images not declared in the plugin.xml, like in this thread:

 public Image createImage(String path) {
   Image image = getImageRegistry().get(path);
   if (image == null) {
     getImageRegistry().put(path, AbstractUIPlugin.
       imageDescriptorFromPlugin(ID, path));
     image = getImageRegistry().get(path);
   }
   return image;
 }
