I've only ever used Terminal sporadically, but I'm having a difficult time
sussing out the right commands to download a single Coppermine album, HQ
graphics only, preferably minus the thumbnails and the webpages (but, seeing
as each time I've tried, I only get the thumbnails, I'll deal with those if I
must).

I realize this is probably super simple, but I've done a search for Coppermine
in the forum and only produced two results.  And while adding -*
+mime:text/html -thumb_* (as suggested from a 2010 post) does diminish the
actual html page downloads, it still downloads only the thumbnails.

This is one of the albums I'm attempting to save, for what it's worth:
<http://www.ssoastro.org/coppermine/thumbnails.php?album=16>

But I've been testing with this smaller one:
<http://www.ssoastro.org/coppermine/thumbnails.php?album=19>

And this is the command I've been using: httrack
<http://www.ssoastro.org/coppermine/thumbnails.php?album=19> -O
"downloads/solar" -* +mime:text/html -thumb_* +*.jpg -*.css s0
