# [NTG-context] Images centered on page

Hello,

How can I center the image on a page? I want images to cover the page completely, and since they have proper size (roughly A4), I only need them to be centered. Now they are stuck to the top, leaving a gap on bottom (and same for left-right).

I have the following script (note my Lua trick to process images in a batch). Image names are "Image00001.png" and so on.

%engine=luatex
\setuplayout
topspace=0mm, backspace=0mm,
leftmargin=0mm, rightmargin=0mm,
location=middle,
height=fit, width=fit]

\starttext

\startluacode
for n = 1, 9 do
tex.print(string.format("\\externalfigure[Image%05d.png]", n));
end
\stopluacode

\stoptext

Best regards,
Vyatcheslav
