Hi! Victor,
   
     The first question:  Whether the pre-defined pictures in Image Library, such as Service,ATM,Node,etc. can be deleted or redefined? And if it can be, how to do it?
     The second question: Would you tell me how to use Actions Configuration?  When I click the Actions Configuration menu, I can only set Name, Type, Options and Command, but I don't know how to set the Command parameter, can you help me?
     Another question:  what is the Package Manager's design purpose and how to use it?
Best regards
