[Plugin: NextGEN Gallery] translate "all" in gallery page

Hi,

I have managed to translate the whole of my site except one word. The “all” showing all tags when you view a gallery – e.g. on this page https://mazine.transparentideas.com/?page_id=8. If anyone can let me know which php file the word all is in I would be very grateful,

thanks

Richard
