Tutorial helps to understand the process of resizing layers with Text-It engine, when some of the layers contain external images generated in OGIM and added to layers. Four layers for image A as well as external OGIM images would be resized and result in image B.
Note: The reason you need to resize layers in Text-It and OGIM and not the downloaded image itself, is because bitmap graphics such as PNG or JPEG would loose quality while resized outside of engine.
