I'm using phpThumb - the PHP thumbnail generator.

'phpThumb.config.php':

$PHPTHUMB_CONFIG['cache_maxage'] = 10; 

$PHPTHUMB_CONFIG['cache_maxsize'] = 1000; 

$PHPTHUMB_CONFIG['cache_maxfiles'] = 10;

but it does nothing... I've got 108 MB in 922 files... and it keeps growing.

For me the solution was really simple. After installing phpthumb with the default settings the line $PHPTHUMB_CONFIG['document_root'] = realpath((getenv('DOCUMENT_ROOT') && ereg('^'.preg_quote(realpath(getenv('DOCUMENT_ROOT'))), realpath(__FILE__))) ? getenv('DOCUMENT_ROOT') : str_replace(dirname(@$_SERVER['PHP_SELF']), '', str_replace(DIRECTORY_SEPARATOR, '/', dirname(__FILE__)))); wasn't uncommeted and all seems to work fine.

BUT: the /tmp directory runs out of space in very short time on a high frequented page.

SOLUTION: It was simple, since phpthumb needs WRITE PERMISSIONS on its $PHPTHUMB_CONFIG['cache_directory'] directory. So be sure that the user who executes your php scripts (usually apache) has the permission to write, otherwise the /tmp directory will be used and filled up with your cached files.

hope this helps!
