+# Icon Manager
+Access the Icon Manager from the main application window via the **View** menu.
+sdrtrunk provides a set of standard icons that can be used in with Aliases 
+(see [Playlist Editor](Playlist-Editor.md)) to display an icon next to talkgroups, individual radios
+and other identifiers.  You can also add your own custom icons.
+
+These icons are used in the **Now Playing** window in the columns where talkgroups and radio identifiers
+are listed.
+
+## Type
+The type column indicates the type of icon.
+* **Standard** - a standard icon that is part of the sdrtrunk application bundle.
+* **Custom** - an icon added by the user.
+* **Default** - the default icon to use for all identifiers that do not have an icon specified.
+

+
+* **Add** - adds a new icon to the list.  Presents a dialog where you select the icon file and the
+name to assign to the icon.
+* **Edit** - edit a custom icon that you have previously added.  Note: you cannot edit standard icons.
+* **Delete** - delete a custom icon that you have previously added.  Note: you cannot delete standard icons.
+* **Set As Default** - assigns the currently selected icon as the default icon.
+
+## Add or Edit Custom Icon
+Click the **Add** or **Edit** button in the Icon Manager window to add or edit a previously added
+icon file.

+
+* **Name** - name for referring to the icon when assigning the icon to various aliases in the Playist editor
+* **File** - button to open a file selection dialog for selecting an icon file.
+* **Save** - saves the current settings.
+* **Cancel** - cancels the add or edit session.
+
+## Icon/Image Formats
+You can add icons from a variety of image formats but the PNG image format is optimal.  Your icon 
+should have a transparent background so that it blends in with the other elements in the display 
+window.
