Something terrible must be done to png pictures, either in ConTeXt or in luatex.
I have the following minimal sample code and picture. I include the png for those who want to check.
% Test png addition.
\starttext
Place png figure.\par
\placefigure{Test figure}{\externalfigure[test.png]}
\stoptext
Without the png-picture it makes an 8KB pdf.
But with the png-picture the pdf swells to 1.8MB.
And that for a png-picture of only 48KB.
Moreover making a zip of all this stuff brought the size back to 110KB.
In the log:
ConTeXt ver: 2011.11.04 14:15 MKIV fmt: 2011.11.10 int: english/english
mkiv lua stats > graphics processing time - 0.001 seconds including tex, 1 processed images
What is done with the png and can it be remedied?
This swelling up of small picture to such enormous proportions makes the inclusion of png-picture nearly impossible, at least impractable.

Can't reproduce here; I get a 70KB pdf with your file and image.
ConTeXt standalone, 32-bit Linux, mkiv, version 2011.10.01 10:48.

Sofar I received 2 reactions.

I've encountered the same problem. The PDF is 1.8MB big. Compressed with qpdf (qpdf --stream-data=compress) its only 60KB!
Latest beta on OS-X 10.7.2
Further search for the cause:
My system is also OS-X 10.7.2 and latest beta.
To find the culprit I reverted to an older version of ConTeXt.
ConTeXt ver: 2011.10.14 22:47 MKIV fmt: 2011.11.11 int: english/english
Now the filesize becomes 72KB instead of 1.8 MB.
This one seems OK.
CONCLUSION: This must have been introduced in one of the beta's later than 2011.10.14 and in or before the current one: ConTeXt ver: 2011.11.04 14:15 MKIV.
I kindly suggest Hans takes a look into the matter.

Hi Hans,
On Mac OS X 10.7.2, testing your file I get afile of 110 KB with mkii, and 72 KB with mkiv (from the minimals). You can find the outputs here:
http://dl.dropbox.com/u/4316076/test-png-mkii.pdf
http://dl.dropbox.com/u/4316076/test-png-mkiv.pdf
All this with ConTeXt ver: 2011.11.29 23:11 MKIV fmt: 2011.12.2.
Best regards: OK
