Editing images is similar to working with other elements. They can be resized manually, or automatically within proportions of the overall shape size.
Images can also be swapped out using the drop down or browser menu.
Unique to images is the option to display the file in "Scaled" or "Tiled" mode. When scaled the image will be shrunk or stretched from its original proportions to the desired size. Suitable for displaying photographs etc.
When Tiled the image will be cropped or repeated to fill the desired size. This allows for seamless texture tiling.
