If you know that your browser can handle image streams of the type 'multipart/x-mixed-replace' but ZoneMinder does not detect this correctly you can set this option to ensure that the stream is delivered with or without the use of the Cambozola plugin. Selecting 'yes' will tell ZoneMinder that your browser can handle the streams natively, 'no' means that it can't and so the plugin will be used while 'auto' lets ZoneMinder decide.
