 ===== The Gradient Overlay Mask =====
-When the cropped image is placed above the background, it is quite annoying to see the **sharp edge** of the image. A better approach is to gradually fade the image at the right and at left edges. This requires to blend the image and the background using a **gradient mask**. We prepared the mask as a PNG image, using **convert** by the ImageMagick suite.
