Есть ли способ автоматически назначать эскизы всем файлам в Wordpress Download Manager с помощью ImageMagick?

Question

Я использую WPDM Pro, и у меня уже есть 1200 файлов, все изображения (PSD, PDF, EPS, JPG). Есть ли способ автоматически назначать эскизы всем файлам в Менеджере загрузки Wordpress с помощью ImageMagick?

Обнаружено решение here Я просто исправляю некоторые детали, и это работает как шарм!
