I'm using the latest texsync'd version of ConTeXt on 32bit and 64bit

alpha channel.
PNG image data, 8-bit/color RGB, non-interlaced <-- works fine
PNG image data, 8-bit/color RGBA, non-interlaced <-- corrupt pdf
PNG image data, 8-bit gray+alpha, non-interlaced <-- following error:

(To benefit anyone coming across this message in the archives:)
As a work around, assuming you don't need the alpha, the image can be
converted to RGB in The Gimp using Layers > Flatten Image.
Alternatively, using Image Magick, the command would be
convert image.png png24:image-new.png
i will update the binaries soon, there has been some fixes and extensions to
pdftex and there will be a new release
