Current render job image sequence location

[tryptophan]

I'm rendering a (tiff image sequence) fairly deep Mandelbrot zoom (1.5E51) and would like to see what the render looks like so far but I can't find the rendered images anywhere on my machine. I'm at about 50% done (started about 24 hrs ago) and now the remaining time is just increasing (14 hrs left this morning and now 21 hrs left) and I just want to make sure its worth continuing with the render. I did find a post from last year saying that it wasn't possible to view the individual images until the render was completely finished I'm hoping now that's changed. Even if I could somehow abort the render and then continue it, if it looks good from where it stopped that would be fine.

thanks
