I have seen the newest org.el. The request below can be done by the patch:

when the cursor on the overlay


C-c C-c


delete the overlay


If you want to recover it , just ‘toggle all latex fragment’, which use the cache too(with little delay).




Is there any problem I left out?

what if search for ‘org-remove-latex-fragment-image-overlays’ in org.el ?  I see it in the function ‘org-ctrl-c-ctrl-c’ (org 8.2.10)

Your patch is about C-c C-c, which is no longer related to
`org-toggle-latex-fragment'. So, it cannot be applied.
