Thanks for the report.

I removed the new interlaced images from libpng-1.6.34, and put some of them back in libpng-1.6.35beta01 (omitting the ones that were rejected by pngimage. As far as I can tell there is nothing wrong with them, but it appears that "pngimage" is having trouble with interlaced images that have bit-depth less than 8.

The troublesome new interlaced files have been removed from contrib/pngsuite in libpng-1.6.34.
