here is the .png (yes it has to be long like that or the hd manila will stretch it)
to cook it in there is a lazy way and proper way. the lazy way is to rename the image "~Avatar-1" then go to oem/oem drivers and replace the existing ~Avatar-1 file (bow the picture will be in my pictures when you go to the settings tab/wallpaper).
the proper way is to place the picture in one of the oem folders you are going to cook in and adding the correct codeing to the intflashes file (or something like that). for more info read rstoyguy's tutorials on how to do this. just look for his thread "custom vga oem requests" in the diamond upgrade forum. and in his post and signature he has a link to "adding files to your rom" or something like that. if you have any questions I'll can try to help you with what i know.
