How to display the image which is in the cache file?

Hi All,

I have installed an extension "Human Captcha" on my site, and add the codes following into the template:

<img src={ezhumancaptcha_image()|ezroot()} alt="eZHumanCAPTCHA" />

But it not works now. I checked the source code, found the url of image is: /var/ezflow_site/cache/ezhumancaptcha/0b371fcfc9ab0ea5ca9a5aa3b2bb17eaf30d293f.jpg. Then i check the folder, found the image is there, but if i view via the url: http://mysite.com/var/ezflow_site/cache/ezhumancaptcha/0b371fcfc9ab0ea5ca9a5aa3b2bb17eaf30d293f.jpg, it failed.

Is there anybody know how to view an image in the cache file? As i guessed the problem may be because of the view privilege of the cache file.

I've finally solved the problem...

In class file ezhumancaptchatools.php I've added line with a chmod function and change directory to store token images to storage, also further in the script, it looks like this>

public static function generateImagePath( $encryptedToken )
{
$ini = eZINI::instance('ezhumancaptcha.ini');
$tokenDirectory = eZSys::storageDirectory() . '/'. $ini->variable( 'GeneralSettings', 'TokenCacheDir' ) .'/';
$tokenFormat = $ini->variable( 'CommonCAPTCHASettings', 'TokenFormat' );

if( !eZDir::isWriteable( $tokenDirectory ) )
{
eZDebug::writeNotice( 'Cache subdirectory does not exist, attempting to create', 'eZHumanCAPTCHATools::generateImagePath' );
eZDir::mkdir( $tokenDirectory );
}
$tokenPath = $tokenDirectory.sha1( $encryptedToken ).'.'.$tokenFormat;
chmod( $tokenPath, octdec( eZINI::instance('ezhumancaptcha.ini')->variable( 'CommonCAPTCHASettings','StorageFilePermissions' ) ) );
return $tokenPath;
}

And in ezhmumancaptha.ini.appen.php I have added under the section CommonCAPTCHASettings this>

[CommonCAPTCHASettings]

TokenStorageFilePermission=0660

And it works actually,
