#The first image shows you the Image viewer window with an image open. To open an image, you can click on Image--->Open.
#Once you click on Image-->Open, you will see a dialog box open as shown in the second image and you can select the image you want to open.

</gallery>
#You can flip the images horizontally or vertically. In the first image you see a horizontally flipped image.
#You can also rotate the images clockwise or counterclockwise. In the second image, the image has been rotated clockwise<br>
These changed display options can also be saved as new images using the Image--->Save as. IIf you use Image--->Save, the existing image will be replaced.
==== Viewing images in Image Viewer ====
A very useful functionality of the Image Viewer application is the view option which allows a display/ presentation of images. When you have a large collection of images, you can show them as a gallery or a slide show. The images below show you the various viewing options
<gallery mode="packed" heights="150px" caption="Viewing images">
File:Imageviewer5.png|Viewing an image
File:Imageviewer6.png|Viewing images a gallery
File:Imageviewer7.png|Viewing images as a slide show
</gallery>
#You can go to the folder of images and click on one image to open with Image Viewer. Once you have opened an image, you can use the arrow keys to click and view the other images. The default view shown in this image is the Best fit view. You can also select View--->Full Screen. The images will be shown in the order in which they are shown in the folder (sorted by the file name). If you would like to see or show the images in a different order, you could do so by renaming the files, and prefixing file name with a serial number. In this case the file with prefix 1 will be shown first file with prefix 2 in its name.
#The second image shows a gallery view of images, with arrows for scrolling forward or backward
#The slideshow option is shown in the third image. You can see a tool bar on top of the slide show which allows you to navigate the slide show. Under Edit-->Preferences-->Slide show, you can set the preferences for the slide show, in terms of time between images and also whether images should be displayed in a loop.
====Saving the files and formats====
<gallery mode=packed heights = 250px>
File:Imageviewer8.png|Save window
</gallery>
We saw earlier that you could change the display option of the images. Once you have changed this, you can click on Image-->Save As and save it as a different file. You can also use the "save as" option to convert the image to a png or jpeg or bmp format through File > Save as option.

====Advanced features====
None
===Ideas for resource creation===
#Images can be flipped and saved and the collection can be shown as a resource for lesson on symmetry, orientation.
#Creating a photo or image essay in the form of a slide show to tell a story
#Using a [[Learn_Record_My_Desktop|screencast recording]] tool to create an audio visual story with pictures and narration
