you may set the background image of Finder to any jpg or png as you like using AppleScript.
I used the great CocoaScript from here: http://www.purebasic.fr/english/viewtop ... 19&t=40684
Code: Select all
Procedure SetBackgroundImage(image.s)
a.s+"set p to " + Chr(34) + image + Chr(34) + #CRLF$
a.s+"set a to POSIX file p" + #CRLF$
a.s+"tell application "+Chr(34)+"Finder"+Chr(34)+#CRLF$
a.s+"set desktop picture to a as alias"+#CRLF$
a.s+"end tell"+#CRLF$
COCOA_AppleScript(a.s)
EndProcedure
datei$ = OpenFileRequester(".",".",".jpg",0)
SetBackgroundImage(datei$)
