The ImageTexture node defines a texture map by specifying an image file and general parameters for mapping to geometry.
The texture is read from the URL specified by the url field using the ImageLoader nodes from the imageLoader field. The texture used will be the first texture that is successfully loaded. Each file in the url field be tried with the first ImageLoader, if none of those succeed the next ImageLoader will be tried on all the urls and so on.
Examples:
Returns the default dimensions to use when this texture is saved to file.
Returns the dimensions of the Image object
