Returns a file handle for image name

Synopsis

• image_open name

Description

NOTE: Image generation is experimental in the current release of NeoWebScript™.

Return a file handle for image name. Name refers to a file in the current directory, including the extension (usually .gd). Makes it possible to access previously generated images. If name is empty, then a handle to the previsouly cached image for the current URI is returned. The user should close the file when finished with it using the \"close\" command. The implementation takes special care not to destroy the old copy of the current image until the current image has been generated.
