[NTG-context] fullpage graphic

[wwl at musensturm.de]

Hallo!

I can not find a solution for the following problem:

I would like to place a floating, framed graphic at the next page 
following the \placefigure[]{}{\framed[]{...}} command.

Problem: The graphicdimensions are (\makeupwidth,\textheight).

Neither the options page, here, force or always help.

If the graphic is a little smaller, so that at least one line of text 
fit on the page, than the graphic gets placed at the right page, else 
the graphic is placed behind the end of the chapter.

Second question:

How can I place a fullpage graphic 
(\paperheight+epsilon,\paperwidth+epsilon) as above
at the next page, and how can I count, but don't display pagenumbers 
for such graphic pages?
