 +=== Zooming ===
 +Showing an image like this is nice, but sometimes you want to zoom in on a detail, get a closer look. To do this Ristretto provides the ability to zoom in on a section of the image. There are several ways to do zoom in on an image,
 +  * The first way to zoom is via the zoom buttons on the side toolbar. It is possible to zoom in, out, to 100% or to make the image fit the screen. These buttons can also be reached via {gui>​Menu>​View>​Zoom}.
 +  * A second way is using the scroll-wheel on the mouse. Moving the mouse-wheel forward while pressing Control zooms in on the image. Similarly moving the mouse-wheel backward and holding Control will zoom out.
 +    <note tip>The zoom-direction of the mouse-wheel can be adjusted, see [[apps:​ristretto:​preferences|Preferences]] for more details.</​note>​
 +
 +  * The third, and last way to zoom on an image is using so-called BOX-ZOOM, or selection-zoom. Press Control+Click,​ and drag the mouse-cursor. This way a box appears, when the mouse-button is released, Ristretto will zoom in on the selected portion of the image.
 +
 +=== Rotating ===
 +Sometimes, it is necessary to rotate an image because it is not positioned in the right orientation. To solve this, you can use the Rotate buttons available via {gui>​Menu>​View>​Rotation}.
 +
 +<note info>​Some digital cameras store the image-orientation inside the EXIF data. If this information is present, Ristretto reads this information and automatically rotates the image.</​note>​
 +
 +<note info>​Ristretto does not provide a way to save the altered orientation back into the file. If you want to modify the image-data, this needs to be done with an image-editor,​ like The GIMP.</​note>​
 +
 +=== Switching between images ===
 +When an image is opened in Ristretto, it shows a list of images in the Thumbnailbar,​ these are the other images located inside the same folder as the currently opened image. The arrow-buttons on the navigation toolbar allow for easy switching between different images.
 +
 +Also, using the scroll-wheel on the opened image, or on the Thumbnailbar will switch to the next or previous image. Allowing for fast and easy navigation between images.
 +
 +== Slideshow ==
 +To run a slideshow of all the opened images, all you need to do is press the Play button. This can be found on the Toolbar and the View menu.
 +
 +<note tip>The duration of the timeout before the next image is shown can be configured inside the [[apps:​ristretto:​preferences?#​slideshow|Preferences dialog]], by default it is set to 5 seconds.</​note>​
 +
 +==== Set as Wallpaper ====
 +It is easy to set the wallpaper on the Xfce desktop directly from the ristretto menu, using {gui>​Menu>​View>​Set as Wallpaper}
 +<figure "Set Wallpaper">​
 +{{ :​apps:​ristretto:​set-wallpaper.png?​nolink&​ |}}
