Hello everybody,

1920 x 1200 wallpapers. Might contain nudity. Look at the 00.index.jpg
for more details on the pictures.

At this moment I have another $TOTAL waiting in queue to be posted.
That is a total of `echo $TOTAL/$NUM_PIC|bc` days, `echo $TOTAL/$NUM_PIC/7|bc` weeks or some `echo $TOTAL/$NUM_PIC/7/4.5|bc` months.

If I reposted other peoples work, my appologies. I do try to keep things seperated as much as possible.

	ps :
	
	There is a hidden message in these postings. This is what you need
	to do to get the message out of the pictures. First you need to
	install http://steghide.sourceforge.net/

	The you need to run the following command in the directory where
	you have saved the files in a terminal or dos window:
	steghide extract -sf <FILE>

	Do not enter a passphrase. What files to use and what they contain
	is listed below. This is more a proof of concept then anything else.
	There will only be plain text files 'hidden' from time to time. No
	virusses, no programs. You can still use the pictures as background.

	And now everybody will ask himself, are there if there were messages
	in all the other postings I did. :-0
