Alright, changing the Content Disposition to 'attachment' (from inline)
helps... When calling directly from FF 1.5 it tries to download, only
writing to the output file once.  Calling from an image tag from any browser
seems to work normally (writing once).

Is there a means of outputting an image with passthru without using
imagemagick or pnm?  I have Imagemagick on this server, but no pnm.  I'd
rather not need either if possible.

Thanks for your time, guys.
