header problem

Den vill inte svälja den här koden... säjer så här

Warning: Unable to create '..\PhotoArchive\A2-0.jpg': Permission denied in /home/leon/public_html/substitute/admin/adminphoto.php on line 56

Warning: Cannot add header information - headers already sent by (output started at /home/leon/public_html/substitute/admin/adminphoto.php:56) in /home/leon/public_html/substitute/admin/adminphoto.php on line 72

jag har satt CHMOD till 777 på katalogen jag föröker köra upp till,

sen får jag ju det här med headers already sent.. det fattar jag inte riktigt vad det innebär?! skulle nån kunna förklara.
