Hi, Andy, and thanks for your help !
I used WM 6.1.
1. I edit my shell.exe and aygshell.dll

try with your own risk)
No risk if you're working out of a XIP archive from the latest MS builds topic.
Copying the files from the \Windows folder to modify them never works (I'm just warning people about that

) : it just crashes Windows Mobile, forcing to a hard reset.
2. Install CHT 2 and soft reset
3. Install volDeus BG Tweak v0.6b4.CAB and soft reset
4. Run volDeus BG Tweak v0.6b4.CAB, select the wallpaper portrait then landscape. Soft reset
5. Start, picture & video, set as today background, set transparency = 0
Wait, wait, wait !!! "Set transparency = 0" ?
Ok... Just got it... I never ever saw that before ! I actually never, ever used "Picture & video" before !
Is that the ultimate trick, then ?
But... It sets up a portrait wallpaper, not landscape (it sets up both, actually)... Will it be vertically cut in the middle and horizontally enlarged (fattened

) as shown on your screenshots ?
Do you think I can "cheat" and put the part I want to display in landscape mode in a reduced (horizontally shrunk) 480 pixels wide picture, with a dummy 320 pixels high part at the bottom, and it will build the stwater_800x480.png picture exactly how I want it to look like ?
That would be really great !
And can I then cheat again, and replace the stwater_480x800.png picture by a more suitable one, without compromizing the bars' appearances in landscape ?
6. Find stwater_640x480.png (for VGA) at windows folder and copy this wallpaper to other folder
7. CHT 2, set wallpaper, all tabs select portrait wallpaper, select landscape wallpaper stwater_640x480.png
Of course ! Got it !
Have fun
I will ! Thanks for the hints ! I'll try all that !
