In this chapter, we started by seeing how to find free pictures online to add to our course materials (and assignments, from a student's perspective) in services such as Flickr and Wikimedia Commons. We then had a look at different ways of inserting images in Moodle, especially using the HTML editor's image upload function. We then started using GIMP for main image editing tasks, such as cropping, resizing, capturing (together with some photography concepts), color correction, photo collage, and saving the images in different formats. Some issues regarding images in Moodle, such as file formats and appropriate sizes, were also discussed and we used GIMP and Jing to collect screenshots. Stripgenerator was also used to easily create comic strips. We also learned how to export PowerPoint presentations to images, adding them to a Moodle lesson, or as an alternative to publishing these presentations in SlideShare. We concluded this chapter by looking at ways to create photo slideshows using Animoto.

Now it's time to put your headphones on! Audio is our next job. We will learn how to find free music and sounds online, understand basic audio formats and settings, use free software for audio editing, extract audio from CDs, create voice recordings, and integrate them in Moodle.
