Hello.. Andre you can get some idea from here :

http://msdn.microsoft.com/en-us/library/ms771331.aspx
or
http://www.codeproject.com/KB/WPF/PhotoViewer.aspx

They also include demo code for picture viewer. Once you can create this kind of app you can easily integrate it with TouchSmart Shell (With the help of TS SDK 3.0). You can also start with the template provided with the TouchSmart SDK to avoid plumbing work!!!

You can use ink API's to create note app.

See demo code here : http://www.codeproject.com/KB/WPF/Ink1.aspx
