Importing Textures

Let's import a jpeg texture to our frame 
Click on the frame to select it 
Click on add map under diffuse 
Click on the box, your uploaded maps are stored inside the editor, so everytime you click on a texture the pick image box will appear.

You can either choose an existing map or you can browse for another a new one. 
Import your image 
Let's add the other texture maps 
Please rename your maps differently when working on other variations to avoid possible name collision and the replacing of a map from another variation with the current one.
