Ich brauche diese Bilder aber in zufälliger Reihenfolge. Ich habe
schon alle möglichen Extensions ausprobiert aber es war keine dabei
die dazu passt. Deshalb wollte ich das ganze jetzt in der Extension
selbst erledigen... aber ich komme einfach nicht drauf wo ich was
ändern muss. Es scheint fast wie wenn es egal ist was ich ändere.
Ich schätze da muss einfach ein shuffle benutzt werden um ein Array zu
erzeugen mit welchem man dann die Bildurls und die Links zu den
Bildern ändert. Nur alles was ich probiere bleibt egal.
Das hier ist die originale tx_imagescroller_pi1.php... kann mir jemand
sagen wo ich ansetzen sollte?
Danke!
Sebastian
