To take screenshots of your creation we recommend a utility named Terrafirma. This utility allows you to view your entire map or just a portion of it and it even allows you to use the default terraria textures. As a demonstration of terrafirma you can look at this websites banner, which was taken using terrafirma then edited using photo software. Terrafirma can be downloaded from: http://seancode.com/terrafirma/

For the time being since this is a very new website we do not yet support hosting of terraria saved game files. However if you post them on an external site you can provide a link to it in the creation sharing forums.
