+# Image source
+Using the image source requires the image-source module.
+{%snippet imagesource-require%}
+The pre-required `imageSource` module is used throughout the following code snippets.
+We also use fs module defined as follows:
+{%snippet imagesource-require-alt%}
+
+## Loading and saving images
+### Load image using resource name
+This is similar to loading Bitmap from `R.drawable.logo` on Android or calling `[UIImage imageNamed@"logo"]` on iOS
+{%snippet imagesource-resname%}
+
+### Load image from URL
+{%snippet imagesource-load-url%}
+
+### Save image source to PNG or JPG file
+{%snippet imagesource-save-to%}
+
+### Load image from a local file
+{%snippet imagesource-load-local%}
