Hi

You can not change the menü-entries by runtime, you can only load a new menü. So you can start with menü1 and load menü2 when you change the picture. When you leave the picture you can load menü1 again. So it works:

1. create menü1 and menü2 in the WinCC Menus and ToolBar Editors (as you did). After that you have menu1.mtl and menu2.mtl
2. change the menüs with the function "HMIRuntime.MenuToolBarConfig = strMTConfigFile"
   p.E. HMIRuntime.MenuToolBarConfig = "menu2.mtl"

I tried it and it works well.
