.jpg/.gif extension problem!

Hi! I have a form that copies a file trough a webpage... (using copy()) But I can't fetch the extension, since php copies the file to c:\windows\temp and calles the file something like phpdfdfe.tmp --> I cant get the extension right (i'm writing it to a db) and the copy() outputs permission denied! Thanx! --------------------------------- Fredrik A. Takle fredrik@takle.net
