 POS Default Empty Image
 =======================
 
-In the point of sale, trying to load known inexistant images 
-is a waste of time.
+This module extends the functionality of point of sale to make PoS load faster
+and to improve products display.
 
+Point Of Sale Load faster
+-------------------------
+
+In the point of sale, trying to load known inexistant images is a waste of time.
 
 When you have 8000 products in your Point of Sale and most of them 
 don't have images, you are happy to save thousands of useless requests:
 the POS load way faster.
 
-Technical information
-=====================
-
-Each time the pos instantiate a product, it will add an
 
-    <img src="'/web/binary/image?model=product.product&field=image_medium&id='+product.id;" />
+Improve products display
+------------------------
 
-The browser will trigger as many requests than there is different url.
+By default, Odoo PoS display a useless generic image for products that doesn't
+have images.
 
+  .. figure:: /pos_default_empty_image/static/description/pos_display_default.png
+     :width: 800 px
 
-If you have many products, the browser will soon reach his limit of 
-network connections to Odoo server and will wait for free slots instead of 
-loading other valuable contents. Then the POS is then very slow to work with.
+With this module, the display of the product is changed, (Size of the name
+is increased for better visibility);

+     :width: 800 px
 
-This module adds a field _has_image in product.template.
+Technical information
+=====================
 
-If product has no image, the product image url is not sent to the POS
+Each time the pos instantiate a product, it will add this code for each product
 
-In the product list, the display of the product is changed,
-          (Size of the name is increased for better visibility);
+.. code:: html
 
-Indeed, if the product has an image, it will load normally.
+    <img src="'/web/binary/image?model=product.product&field=image_medium&id='+product.id;" />
 
-This module is compatible with pos_product_template
+The browser will trigger as many requests than there are different urls.
 
+If you have many products, the browser will soon reach his limit of 
+network connections to Odoo server and will wait for free slots instead of 
+loading other valuable contents. Then the POS is then very slow to work with.
 
-Known issues
