+
+Guest operating system categories are useful for categorizing images, i.e.,
+templates and ISOs, in several UI forms such as deploying an instance,
+reinstalling an instance, etc., when the modern image selection is used in the
+UI configuration.
+
+To allow a guest operating system category to be displayed in the UI forms, it
+must be marked as featured. The order of the categories can also be controlled
+using the Order option in the categories view.
+
+Like other resources, a custom resource icon can be set for a particular guest
+operating system category for further control. If no resource icon is set for
+a category, the UI will display default icons based on the category
+name.
+
+An existing guest OS category can be deleted if it does not have any
+associated guest operating systems.
+
+The "Add guest OS category" option allows operators to create new categories,
+which can be marked as featured if they are meant to be displayed in the UI
+forms.

+Instance Image Selction Customisation
+-------------------------------------
+
+In the UI, there are several forms where the user needs to select an image (template/ISO) for an instance, such as deploying an instance, reinstalling an instance, creating a VNF appliance, etc. The image selection interface for these forms can be selected by the operator based on preference by specifying properties in the UI configuration file (config.json).
+
+The configuration property _imageSelectionInterface_ can be set to one of these values: modern or legacy. The default value is *modern*.
+
+When the *modern* interface is used, images will be categorized based on the guest operating system categories. Further customisation can be done using the configuration properties showUserCategoryForModernImageSelection and showAllCategoryForModernImageSelection to allow or disallow the display of additional categories.
+
+|ui-modern-image-selection.png|
+
+The *legacy* interface will display images based on templatefilter/isofilter, i.e., Featured, Community, My Templates/ISOs, and Shared.
