No problem - if you really have to change the image on a daily basis
I'd probably just do it by saving a cookie on the client's PC
containing the date that the image was last updated and then compare
it against the current system date.
They might not have cookies enabled of course, but in that case you
can prevent the image changing on every page refresh by using the
session method as a backup.
