Help: Splash Screen that uses cookies

[Azoka_Theo]

this is what i want you all to help me with.

most of us have visit forbes website we see the splash screen while later redirect to the allocated url of that distinguished post…

now i want something like that. but i dont want it to redirect. i want it to dismiss if the person does not click the text " continue to site" for 9 sec. and after that it wont show again except the person clear his or her browsing history and cookies.

a friend of mine gave me this code which i implemented on my header.php via wordpress.

`

` which i implemented. happily enough the code works. but my problem is that it shows every time which is very annoying to users
