provided its the right format. just save the .BMP file to your PC.
then copy/move the file into the program directory folder named "splash".
Example location: "C:\Program Files\Dashhawk v2\Splash\"
then plug ur DH into ur PC, start up the MSD program.
select the "Edit Splash Screen" option, then "import" and select the folder you placed the file in and select the file. blamo! No say choose the "update to dashhawk" button or whatever it says.
Ok, I get the general gist, but I am talking about a file I already have on my DH, so I will customize the above to copy it from my DH to my computer, then post it here to share. It looks like a scanned photo; I think you'll like it.
