Kimlik doğrulama veya yönetimden onay bekliyor.Merhaba arkadaşlar. yeni sitemde evid diye bir tema kullanıyorum. Tema da şöyle bir özellik var. her yazıya ufak resim koyabiliyorsunuz. Özel bir alan ekledim. Ancak değer kısmına ne yazsam resim çıkmıyor. Yani yanlız yere koyuyorum resimlerimi. Kodunu veriyorum. acaba nereye atmam gerek resimleri.?

ben bu şekil yaptım fakat bu thumbları
<img src="http://www.xxx.com/media/videos/tmb/35/default.jpg" alt="" width="0" height="0" />
şeklinde alması için ne yapabiliriz?
bot bu şekilde çekiyor ama thumb lar görünmüyor
Yazı içerisine bu kodu eklersen thumblar sorunsuz gorunecektir.Özel alana gerek yok - 09-09-2009, 08:44:33thumb olarak görmüyor işte sorun oradaCodeking adlı üyeden alıntı: mesajı görüntüle
