Woops ! I'm sorry for these two post. The solution has been posted two years ago :

(thanks to marcan)

And the code to hack is still on line here :

It works fine with these instructions (INSTALL.txt) :

add a line into original imagemanager.php like this:
line 28:
---------------------------------------------------
include './mainfile.php';
include 'modules/myalbum/imagemanager.php'; // add this line
if (!isset($HTTP_GET_VARS['target']) && !isset($HTTP_POST_VARS['target'])) {
exit();
}


And maybe for the next release it will be useful to add marcan's modification (class/module.textsanitizer.php around line 180)
