I'm not sure why these are getting converted to a .dat attachment instead of an
inline image...

This site apparently appends .dat to files it doesn't recognize I think (or
maybe file extensions it doesn't recognize). I put a few binaries in the
binaries section and the .bz2 files I uploaded all have .dat appended, but the
..gz files and .tgz files don't.

Seems both of you are using the web-interface. Be aware that you can
also get a native view of the newsgroups with a newsreader.

For some reason, .dat is added to the image when the post is addressed 
on the POV-Ray site, but not when addressed from Thunderbird. And only 
for these images by Bald Eagle. Strange.

It /might/ be because - surprise! - they're not PNG files at all; they 
have a .png extension, but really they're BMP files.

Indeed they are:

BrickPattern.png: PC bitmap, Windows 3.x format, 640 x 200 x 24

Actually, I'm kicking myself for not noticing immediately. The size is a
big giveaway: 375 KB versus 65.1 KB.

A true PNG is attached to demonstrate the diffence.

BTW Bald Eagle, you need to change your ini file settings to generate
true PNG images
