Sorry for the long delay in responding but new projects kept getting in the way of "fixing" this on our existing sites.
In PS 6.3 the Xinha editor setup functions have been rewritten so the location to add ImageManager or ExtendedFileManager has changed. To get ImageManager or ExtendedFileManager working with PS you need to change the following line in guppy.js at or around line 401.
var xinha_plugins = ['TableOperations'];
to
var xinha_plugins = ['TableOperations','ImageManager'];
or
var xinha_plugins = ['TableOperations','ExtendedFileManager'];
This will initialize the image manager plugin when the Xinha editor starts.
I found I also had to change the .htaccess file in the guppy directory to allow browser access to php files. I had to change the following line:
SetEnvIf Request_URI "\.(htm|html|gif|css|js)$" object_is_ok=1
to
SetEnvIf Request_URI "\.(htm|html|gif|css|js|php)$" object_is_ok=1
I have not investigated the security implications of this change as yet. The plugins call a php script where the table operations plugin only calls a javascript file.
For those interested I also loaded the latest version of the ImageManager plugin from the Xinha project and had to make the following changes for a Linux/Apache install:
In config.inc.php find the following line:
$IMConfig['images_dir'] = "demo_images";
and change to
$IMConfig['images_dir'] = $_SERVER['DOCUMENT_ROOT'].'/image_store/';
Also find
$IMConfig['images_url'] = str_replace( "backend.php", "", $_SERVER["PHP_SELF"] ) . "demo_images";
and change to
$IMConfig['images_url'] = $_SERVER['HOST'].'/image_store/';
Of course change the "image_store" directory to your actual image folder as always.
I hope this helps those looking to add file system image uploads & inserts along with the standard Photoshare and Mediashare options.
