Dikkat edilmesi gereken noktalar, öneriler;

• dosya yüklemesi söz konusu olduğunda form içinde enctype tanımı
• resize özelliğinin sorunsuz çalışması için PHP’nin GD destekli kurulduğundan emin olun.
• Güvenlik kaygısı nedeniyle, yükleme yaparken uzantı kontrolü yapmayı unutmayını
• Dosya adlarının çakışmaması için md5(micro_time()) fonksiyonlardan faydalanabilirsiniz.
