perms of images

installation: adjust paths and names in exifperms.sh and Makefile and
make install (eg to public_html)

usage: exifperm.sh `ls *jpg *JPG *jpeg | grep -vE "_small|_med|_old"`

needs .htpasswd and .htgroup or similar (see header of exifperms.sh
to adjust names)

extras: 

rotate.cgi (for rotating, editing comments, refreshing pages: CAVEAT
	access permissions, not set automatically! needs referer to work, uses
	comment_add.sh for jpeg comments)
comment_add.sh (depends on rdjpgcom and wrjpgcom)

.htbase is included in .htaccess to tweak permissions

.private.header.html and .header.html are included in html if existent

dependencies:
libjpeg-progs: /usr/bin/rdjpgcom
libjpeg-progs: /usr/bin/djpeg
netpbm: /usr/bin/pnmscale

and of course apache and the usual unix utilities (find, ls, rm, ...)

only for (deactivated) rotate.cgi:
exiftran: /usr/bin/exiftran
(lossless jpeg rotation)
