To access your media assets in MAM, click the filter drop down, and select Media from the list.
You can scroll back and forth through your existing media assets in the Media Assets carousel, by clicking the back and forward arrows.
If you wish to view all of the media assets that you have uploaded to MAM, click the See All link in the top-right corner of the Media Assets carousel. You are then taken to the Browse: All Media Assets section, where you can see a complete list of all your assets, ranging from newest to oldest.
