Angiv mappe at vise billeder fra
Hej, som sagt så vil jeg bestemme fra hvilken mappe den skal vise billederne. Scriptet laver thumblines af alle billederne der ligger i samme mappe som den. Har lagt den i en anden mappe og bruger så include, men så "tror" filen at den er i roden af biblioteket og viser de billeder der er der, i stedet for den mappe den ligger i.Så hvad skal jeg ændre for at bestemme hvilken mappe den tager billederne fra? Kan man overhovedet det når jeg bruger include? Hvad kan jeg ellers gøre?
