Configuration

Configuration is instance-wide Extension Configuration. Edit it under Settings > Extension Configuration > imaginator in the backend, or set it in config/system/settings.php:

config/system/settings.php

$GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['imaginator'] = [
    'lqip' => 'dominant-color',
    'ladder' => '320,640,960,1280,1920',
];

Note

Settings are global by design, so the render path and the signed-endpoint verify path always agree. A per-site model would risk mismatched ladders and spurious 403s.
