[How can I put my picture in a portal ?]

Hi I am fairly new to trying to edit a mesh or texture with nifscope or other tools.  I have a few things I have managed to accomplish but need help with this one

 

I have seen this down on wayshrines with some shader effects that make it warble.  I am just looking for a flat nif square that displayer on one side my picture and is

 

see through on the other side ?

 

I have a picture located here  that I would like to have on a portal screen which I can place in front of a door.   If anyone knows how to do this I would be extremely grateful

[Test for DLC]

Thank You for that code above. Works great...

Id like a mesh (nif)  that will display this dds in skyrim ?   Similar to the wayshrine portal picture.  I do not know how make that file  ?  

[Test for DLC]

I have an example of script below which assembles with no errors but doesn't work

 

I am missing something but I want to test if dawnguard is installed.   What do I need to modify to make this work ? 

 

Bool[] Property bDLCIsLoaded Auto ; Element 0 is bDawnguard, etc.
Int[] Property iKnownFormID Auto ; Element 0 is 2048 for Dawnguard's DLC1AurielsBow "Auriel's Bow" [WEAP:02000800], etc.
String[] Property sDLCName Auto ; Element 0 is Dawnguard.ESM, Element 1 is HearthFires.ESM, element 2 is Dragonborn.ESM, etc.
 
Function CheckForDLC()
    Int iIndex = sDLCName.Length
    While iIndex
        iIndex -= 1
        If bDLCIsLoaded[iIndex] != Game.GetFormFromFile(iKnownFormID[iIndex], sDLCName[iIndex])
            bDLCIsLoaded[iIndex] = !bDLCIsLoaded[iIndex]
            If bDLCIsLoaded[iIndex]
                Debug.Trace(sDLCName[iIndex] + " is loaded")
                If iIndex == 0 ; Dawnguard
                    ; Make any changes needed for Dawnguard
                ElseIf iIndex == 1 ; Hearthfire
                    ; Make any changes needed for Hearthfire
                ElseIf iIndex == 2 ; Dragonborn
                    ; Make any changes needed for Dragonborn
                EndIf
            Else
                Debug.Trace(sDLCName[iIndex] + " was loaded, but is no longer")
                If iIndex == 0 ; Dawnguard
                    ; Revert any changes previously made for Dawnguard
                ElseIf iIndex == 1 ; Hearthfire
                    ; Revert any changes previously made for Hearthfire
                ElseIf iIndex == 2 ; Dragonborn
                    ; Revert any changes previously made for Dragonborn
                EndIf
            EndIf
        EndIf
    EndWhile
EndFunction
