I'd prefer something more closely resembling `org-latex-preview'
approach with prefix arguments:

    Toggle preview of the LaTeX fragment at point.
    
    If the cursor is on a LaTeX fragment, create the image and
    overlay it over the source code, if there is none.  Remove it
    otherwise.  If there is no fragment at point, display images for
    all fragments in the current section.  With an active region,
    display images for all fragments in the region.
    
    With a C-u prefix argument ARG, clear images for all fragments
    in the current section.
    
    With a C-u C-u prefix argument ARG, display image for all
    fragments in the buffer.
    
    With a C-u C-u C-u prefix argument ARG, clear image for all
    fragments in the buffer.

`org-toggle-inline-images' should also be changed.
