The images I use is a B&W monochrome BMP.
I just created it in paint, unfortunately I don't have it available on this computer.
You can create it in a matter of 4 minutes.
Just create a new document in paint with 600x800 resolution.
Then draw a line on the top.
Select the drawing (CTRL + A), and copy paste it (CTRL +C, CTRL + V) 2 pixels lower (I found it works best when zooming to 200 or 400%).
Once you have 2 lines, just continue copy/pasting the whole image.
At first it seems to take long, but as soon as you have the second line correct, work goes quite fast (1 line, 2lines, 4lines, 8lines, 16, 32, 64, 128, 256, 512,..).
Should take you 12 steps.
The painfull process starts when you are going to decrease the resolution.
I save the BMP as 600x800. Then take of 1 pixel from the bottom and from the side.
Save that one as 599x799.
This process takes a lot of time, and leaves you with a lot of BMP's.
I'm still in the process (while doing other things).
Unless you got a great photo editor that can autocrop and save for you, most work will be done manual.
If you want to, I can prepare the BMP's and RAR them, but that 'll most likely not be before next week!
