<?php
    public function route()

        $segments = server_request()->getUri()->segments->getArrayCopy();

        if (false !== ($key = array_search('images', $segments))) {
            $segments = array_slice($segments, $key);

It seems like $key can also be of type string; however, parameter $offset of array_slice() does only seem to accept integer, maybe add an additional type check?

        } else {
            array_shift($segments);

The property input does not exist on O2System\Framework\Http\Controllers\Images. Since you implemented __get, consider adding a @property annotation.

            $this->imageCrop = true;

            $segments = array_values($segments);
        }

$extensions was never initialized. Although not strictly required by PHP, it is generally a good practice to add $extensions = array(); before regardless.

                $imageFilePath = str_replace('.' . $extensions[ $i ], '', $imageFilePath);
            }
        }

        $mimes = [
            'gif'  => 'image/gif',
