It's really quite simple. Let's say you have a black and white photo of a Corsair like those in your post that you want to upload. Make sure the picture is saved to your hard drive. Go into the Black and White Photo section, and click the upload button. Fill out what you want the picture to be called (i.e: Corsair) and a description (i.e An F4U-5N). Descriptions are optional. Last, browse through your computer to find the picture, and when you find it, select it. When you're ready, click upload. It should work.
Nice! That's Vought F4U-5N Corsair of USMC VMF(N)-513 "Flying Nightmare" and I believe they flow in Summer 1951. Their bases at K-13 or Kimpo, Korea and they supposed protecting F-80s and F-86s at night. Excellent picture you found Zamex.
