[quote="ktbcrash"]You can try using tbone's SelectEX addon along with his Create random folder.jpg script to help automate the folder.jpg creation.
You just need to select the folders you want the folder.jpg to be created for and click the button. You do need to wait for the script to run though. You can watch the Modified date change on the folders it's finished on.
You can also adjust the % down to 1% to help keep the random selecting near the beginning of the list (depend on how many files are in the folder of course).[/quote]
ok the create random folder script is working perfectly as expected, one more request. the folder is displayed with the folder icon around , the yellow windows color folder. is it possible to have as a folder displaying something specific, like it's done with mp3 filder, or film ones ? and not having a window icon around the picture ? like it's displaying a poster or a dvd case as a folder ? i'm close 
thanks guys !
