Hi
I'm getting the following error with PNG images:
libpng error: PNG file corrupted by ASCII conversion
!LuaTeX error: libpng: internal error
==> Fatal error occurred, no output PDF file produced!
minimal example
---
\starttext
\placefigure{}{\externalfigure[mill.png]}
\stoptext
---
LuaTeX in minimals beta-0.70.1-2011051923 (rev 4277) and latest trunk beta-0.71.0-2011061600 (rev 4301) are both affected.
Adam

mill.png itself seems to be corrupted. E.g., display complains:
improper image header `mill.png' @ error/png.c/ReadPNGImage/2957.

~$ pngcheck -v mill.png
File: mill.png (154867 bytes)
File is CORRUPTED. It seems to have suffered DOS->Unix conversion.
ERRORS DETECTED in mill.png
...that's what pngcheck says.
