Wordpress class-wp-image-editor.php permission denied -

i changed directory of wordpress instance. copied files via ftp new folder , copied database , edited site url , home entries.

now page don't show images, gives me message:

warning: imagejpeg() [function.imagejpeg]: unable open '/www/htdocs/serverid/wp-content/uploads/bfi_thumb/modell3-2xr5ffo5juzmz3rgn84d8g.jpg' writing: permission denied in /www/htdocs/w00db707/wp-includes/class-wp-image-editor.php on line 405

everything else looking good. know whats wrong?

two possibilities:

the file/folder permissions /wp-content/uploads/ need chmod 0755 or 0777

if permissions set 0755 or 0777, owning user/group needs match httpd user (varies based on server configuration; user www-data, apache, if plesk environment username setup subscription with)
