Skinning Images
From GSC Wiki
GSC loads the images as defined in the skin XML when the program starts, and when a skin change is performed by the user. GSC does not offer rendering control on a per image basis (eg: tiling, patterning, custom blitting). GSC internally decides how images will need to be rendered and will render an image in whatever manner is defined in the program itself (Although we are looking toward opening this type of customization in the future). This results in having to comply with the current GSC skin format until extra customization functionality is introduced.
If an image is missing from the skinning XML: GSC will not crash, but may instead choose not display the component for which that image pertains to. It is recommended to test your skin when new iterations of GSC are released to ensure the best compatibility.
