Özel Alanla İlgili Bir Sorun Var

Arkadaşlar özel alanla resimleri thumbnail çekiyorum. Ama aynı resmi 2. kere çekmiyor neden acaba her dafasında farklı isimde tekrar eklemek zorunda kalıyorum yardımdı olabilecek var mı?

normalde aynı resmi istediğiniz kadar çekebiliyorsunuz.sizin kullandığınız timthumb.php de bir sorun olmasın.yinede çok fazla bilgim yok bu konuda ama bilen arkadaşlar çıkacaktır.

timthumb.php yok ama Tema fonksiyonları (functions.php) verim ben acaba bakıpta cevap verebilecek olan olursa sevinirim
