[NTG-context] columns and pictures

(Warning: I'm a ConTeXt newbie. I started using ConTeXt specifically because this is quite difficult to do in LaTeX, along with some other DTP-ish things.) I'm trying to place pictures at a specific position on a page in a multicolumn document, something like this (T: text, P: picture): TTTTTTTTTT | TTTTTT PPPPPPPPPPPPPPPP TTTTTTTTTT | TTTTTT PPPPPPPPPPPPPPPP TTTTTTTTTT | TTTTTT PPPPPPPPPPPPPPPP TTTTTTTTTT | TTTTTTTTTT | TTTTTTTTTT TTTTTTTTTT | TTTTTTTTTT | TTTTTTTTTT How can I do this in ConTeXt (if it's currently possible)? -- Brian P.
