What I did was this:
Code:
convert escher01.png -quantize GRAY +dither -colors 16 -rotate "-90>" escher01.bmp
You can install imagemagick and use the convert command even in Windows.

Hello, I'm making a logo for my 902 while expecting (I can't knit). I've set the res to 825x1200 (found on the shop page) and set the mode to grayscale.

Now:

When I try to save my pic as .bmp, Photoshop asks me the file format (Windows/OS2). Which one should I choose?
Also, do I really need to convert from grayscale to indexed color?
Since the screen has 16 levels of gray, can't I just save it with a 4-bit depth?

I was not very fast, but now I've published a web app and a desktop app to convert images for your pocketbook:

1) Open the picture you like to convert with IrfanView

** to fit the picture to the screen you should turn picture to get 600x800 resolution, turn the picture with the keys "L" and "R"
3) Do "Image->Convert to Greyscale"
4) Press "I" and change the dpi to "96x96" (important to see full 16greyscale colors on PB!)
5) Press "S" and choose "Fileformat" BMP, save it any location you like
6) Transfer the created file to "/system/logo" on your Pocketbook
7) Choose your logo at the Settings
8) Enjoy

very helpful tutorial for me: it wasn't working with either GIMP or Paint (though again might be due to my inability, couldn't see how to set the 96x96 option), but irfanview did the trick
p.s.
for teh large models, use 825x1200 as suggested by PossenteSpirito
