+New driveropts= option "tattoofile=". Use together with -checkdrive 
+to write an image of the right size to disk.
+
+	DiskT@2 hints:
+
+	In order to have "DISKTATTOO" listed in the "Driver flags",
+	the disk currently inserted must be usable for the DiskT@2 feature.
+	This means that there needs to be enough space on it.
+
+	You need an B&W image with 3744 pixels per line
+
+	Best start with a 3744 x 320 pixel image.
+	The correct size may be retrieved with
+		wodim driveropts=tattooinfo -checkdrive
+
+	To get RAW image data:
+
+	-	Take 'xv' and save the image in PBM/PGM/PPM (raw) mode
+
+	-	use a binary aware (must support unlimited linelength)
+		editor such as 'ved' and remove the header lines.
+		These lines look like:
+
+		P5
+		# CREATOR: XV Version 3.10a  Rev: 12/29/94 (PNG patch 1.2)
+		# CREATOR: XV Version 3.10a  Rev: 12/29/94 (PNG patch 1.2)
+		3744 144
+		255
+
+		Now you should have (in case of the file above) a file that
+		has exactly 539136 Bytes.
+
+	-	Note that the tattoo image must be left to right flipped
+		(a mirror image).
+
+From a hint from "E. Robert Bogusta" <rob23@tmr.com>: 
+
+Take an image, and do:
+
+  djpeg myface.jpg | ppmtopgm | pnmflip -lr | 
+    pnmscale -xsi 3744 -ysi 320 | sed '1,/255/d' >myface.tattoo 
+ 
+So: 
+  djpeg extracts ppm from a jpeg. Use your favorite other way of getting 
+this far is you wish. 
+ 
+  ppmtopgm changes color to grey scale 
+ 
+  pnmflip -lr flips left to right, the small image is faster 
+ 
+  pnmscale makes it 3644x320 regardless of starting size. This may make it 
+look really odd on the CD if it doesn't start off the right size. More on 
+this after I try it. 
+ 
+  sed strips from the first line to the line containing 255, which is the 
+last header line. 
+ 
+Note that it would be better to use the actual height of the applicable image instead
+of the maximum value of 320 and it would be even more correct to create an
+image that has the right width/height ratio for the target on CD in order
+get an undistorted view of the image on CD.
+
+For best visibility, use black text on light background.
