Re: freeing resourses after the end of the session

I made a image validation code, wich generate a image every time the user enters a page. The name of the image uses the session id, and I save it in a temporary directory. When the user close the browser (or leave the site) I would have to delete the image (or else I will start to have many garbage images in the temp directory). Is there any way to do that? From PHP?
