DOES ANYONE KNOW HOW TO DELETE A POST?

HI everyone. i had a problem with a post. only one photo of several actually appeared when i posted (despite the fact that it looked as intended in the preview) .. so i thought i would either fix the problem or delete it and start fresh.

I couldn't do either. ended up just editing the post completely into the one you are reading now.

Does anyone know how to delete a post?
does anyone know why only one picture actually appeared on the final post. (even though they all showed up on the preview)

THANKS EVERYONE

GLAD TO SHARE THEM WITH YOU. THANKS!
