In this tab two kind of sources are shown: the source pictures from which to create the mosaic, and the commercial pictures and video files to be shown at regular intervals ('Interludes'). The source pictures are loaded in a predefined folder on the hard drive. The precise location must be indicated in the tab 'Admin' sub tab 'File locations'. When a non-valid location is found or no source files are found the application may not run properly!

Each picture of video thumbnail picture has a check box in the left top corner. Only the checked pictures will be taken into the dynamic views. These checks are not saved in the project file, and has to be managed manually each time the application is started. To avoid extensive (un)checking the show technician better only puts the valid files in the indicated folders. The sub folders of the directories will not be read, so it's a convenient way to store un-used pictures in a sub folder.

The 'Source files for video and stills' may contain video and picture files. The application will try to auto detect if the commercial is a still message (picture file) or a video. And then starts either a transition to a video or to a photo. In case the sound of a video file should be mute you need to check the box 'Mute audio signal' .

Double-clicking on a source picture will select that picture for the mosaic. The mosaic is not generated automatically, and although this pictures is shown in the GUI the technician still has to made the initial mosaic manually by pressing the 'Initial Mosac' button.

There are two ways to show the sources overview: the listview and the thumbnail overview. The latter being explained above. The listview has a couple of extra functions. When a video file is found (file extension .avi) it will also show three video player buttons (stop, play, pause).
