You can take screenshots by pressing F2 while looking at it. Then locate your screenshot folder, and upload the images to your profile.
To make a map, locate your .minecraft folder (your screenshots folder is in here as well) and go to "saves". This is where all of your worlds data is kept. find the world/save that you built moria in, copy it, and there you go! now anyone who you give this save to can put it into their saves folder to play it, as long as they have the lotr mod, or any mods that were present when you made the world. then, if you want others to be able to download it, upload the file somewhere where others can download it.
p.s, to get to your .minecraft folder on windows, click start, and in the searchbar type %appdata%, then click the file "Roaming". your .minecraft folder should be the top file in there.
