Re: terrible png placement

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
