Web'de şöyle bir şey buldum. İstediğiniz text i image olarak sayfaya basabiliyoruz.
Fakat bir kısmını değiştirmek istiyorum. Script arkaplanda random renkler oluşturarak yazdığınız yazıyıda ekleyerek imaj yaratıyor.
Ben bu random renkler yerine sabit bir png arka plan olmasını istiyorum. Yani bir adresten img/foto-arkplan.png gibi.
