Buyocat Posted June 29, 2006 Share Posted June 29, 2006 Put the header (blah blah blah ) first. You can't have that HTML before it. Link to comment https://forums.phpfreaks.com/topic/13240-cannot-modify-header-information/#findComment-50973 Share on other sites More sharing options...

wildteen88 Posted June 29, 2006 Share Posted June 29, 2006 Also if you are creating an image it is pointless having any HTML in the file that is creating the image. As you cannot create an image and use html or any other text at the same time. So remove all html.
