The 'albums' directory (located in the directory where you uploaded Coppermine) should be writable in order to allow pictures upload. Use your FTP program to change its mode to 777.
How i change ITS mode to 777 in dreamweaver?
You can't do it in Dreamweaver. Use an FTP client.
where can i download a free one?
CuteFTP at http://www.cuteftp.com/downloads/cuteftp.asp
SmartFTP at http://www.smartftp.com
Filezilla at http://sourceforge.net/projects/filezilla
thanks
Note: you mustn't use Dreamweaver to upload coppermine files. If you already did, re-upload them using a proper ftp client.
