gui.drawImage implemented. It needs a Path, X and Y Points, Width (optional) and Height (optional). If Width or Height are null, their value will change to the original Width/Height. As with gui.drawIcon, the Path needs double backslash (\\).

Take in mind that if the image have transparent background, the background will be drawn in transparent.
