In my installation the "Auto rotate image" check box remains grey and can't be checked. I also tried a fresh install with the same result. I use PHP 5.2 Is there a trick that I couldn't find yet? Thanks in advance.
The actual test is for the presence of a function named `imagerotate` in PHP. So maybe your php has this configured out. It is supposed to be available since 4.3.
Iti s not automatically availabe in PHP 4.3 or newer. According to www.php.net: Note: This function is only available if PHP is compiled with the bundled version of the GD library. http://www.php.net/manual/en/function.imagerotate.php
