To test either version of Media Viewer, click on the small 'Beta' link next to 'Preferences' in your personal menu. Then check the box next to 'Media Viewer' in the new BetaFeatures section of your user preferences — and click 'Save' (see screenshot). You can turn off any this options anytime, by reversing these steps. To test a variety of images in different file formats, you might like to check this Lightbox demo page.
