I prefer to generate such files and "trash" them at the end of a
successful run (by moving them to a directory under /tmp).
I don't know what system you're using, but it's straightforward in
linux to write a script to run LP that does this for you, and saves
you a lot of typing in the command line.

Not using PNG files, I don't have your particular problem, but my
script tees the console output into a .log file. If the file contains
the string "ERROR", the .log file is renamed .error and kept, whereas
otherwise the .log file is "trashed".

An example where I do have your problem is with pdflatex, which not
only writes .aux and .log files, but leaves them world-writeable.
(Maybe it's been fixed—I don't bother checking.) Here, it's
important not to actually delete the .aux file, because it's required
for final production of documents that have TOCs or forward references
etc, but it's not needed in 99% of my pdflatex runs.

Cheers,
David.
