~~Title: Viewing Images ~~
<pageheader/>

Opus has two main image viewers. Both can be used to view images, movies, documents and other formats for which a plugin exists.


==Viewer pane==
There's the integrated [[:basic_concepts:the_lister:viewer_pane|Viewer Pane]], which is embedded within a Lister:


{{:media:13:viewer_pane.png?nolink|}}

==Standalone viewer==

There's also a standalone (floating) image viewer.

{{:media:13:standalone_viewer.png?nolink|}}

The main difference is the [[:basic_concepts:the_lister:viewer_pane|Viewer Pane]] is tied to a Lister whereas the standalone viewer acts almost like a separate utility. The standalone viewer also has basic image editing functions which the viewer pane does not.


==Accessing the standalone viewer==
You can access the standalone viewer in several ways:

  * If the **Use internal picture viewer** option on the **[[:preferences:preferences_categories:file_operations:double-click_files|File Operations / Double-click on Files]]** page in Preferences is turned on, double-clicking on a recognized image file will open it in the standalone viewer.

  * The **Slideshow** button on the default toolbar will launch a slideshow of all images in the current folder, using the standalone viewer. The speed of the slideshow is controlled from the **[[:preferences:preferences_categories:viewer:standalone_viewer:slideshow|Slideshow]]** page in Preferences.

  * The internal **[[:reference:command_reference:internal_commands:show|Show]]** command will display selected files in the standalone viewer. This command is available on the drop-down menu attached to the **Slideshow** button.\\

  * From outside of Opus, you can use the `d8viewer.exe` or `dopusrt.exe /show` commands to open files with the Opus viewer. 


==Options for the standalone viewer==
There are a number of options that control the appearance and behaviour of the standalone viewer. These can be found in the **[[:preferences:preferences_categories:viewer|Viewer]]** category in Preferences. By default, the viewer will:

  * Auto-size to fit every picture - as you step through images, the window will resize if needed to display the picture. 
  * Open centered on the current monitor. 
  * Display a frame around the picture (as in the above screenshot). 
  * Show or hide the scrollbars while viewing images. 
  * Automatically build a list of all other pictures in the folder, when opened via a double-click on an image file (with an additional option for the list to wrap-around when you reach the start or end). 
  * Automatically rotate images to compensate for the EXIF orientation tag, saved by most digital cameras. 

These options can all be changed from Preferences.
