How to hide the View triad in the bottom corner when using doing an "Export Image".
Solution
This cannot be done in the actual export image function itself.
You need to do this before you export the image by going to File --> Preferences --> Visualization --> View --> Decorations --> View Axis --> "show view triad" - Toggle off the check box in front of this, and press Apply/OK.
Now you can export the image of the graphics area.
After this you toggle it on manually again the same way.
Extra: To hide the WCS, simply press "W" to hide and unhide the WCS.
