Phpthumb不存在url重定向与.htaccess

Question

是否可以重定向，如果在url "src=nothere"指定的图像不是我需要重定向到不存在的图像或类似的东西的实际路径。我有一个问题在决定在这里使用正则表达式?以及如何知道它是否存在。

您是否使用phpThumb类?

phpThumb.config.php

    // * Error message configuration
$PHPTHUMB_CONFIG['error_image_width']           = 400;      // default width for error images
$PHPTHUMB_CONFIG['error_image_height']          = 100;      // default height for error images
$PHPTHUMB_CONFIG['error_message_image_default'] = '';       // Set this to the name of a generic error image (e.g. '/images/error.png') that you want displayed in place of any error message that may occur. This setting is overridden by the 'err' parameter, which does the same thing.
$PHPTHUMB_CONFIG['error_bgcolor']               = 'CCCCFF'; // background color of error message images
$PHPTHUMB_CONFIG['error_textcolor']             = 'FF0000'; // color of text in error messages
$PHPTHUMB_CONFIG['error_fontsize']              = 1;        // size of text in error messages, from 1 (smallest) to 5 (largest)
$PHPTHUMB_CONFIG['error_die_on_error']          = true;     // die with error message on any fatal error (recommended with standalone phpThumb.php)
$PHPTHUMB_CONFIG['error_silent_die_on_error']   = false;    // simply die with no output of any kind on fatal errors (not recommended)
$PHPTHUMB_CONFIG['error_die_on_source_failure'] = true;     // die with error message if source image cannot be processed by phpThumb() (usually because source image is corrupt in some way). If false the source image will be passed through unprocessed, if true (default) an error message will be displayed.
