Die Sache ist ja, dass eigentlich alles super fuktioniert. Es werden Bilder gemacht, die werden richtig zusammengefügt und alles.
Ich habe den Code mal angehängt. Es wäre cool, wenn ihr euch das noch einmal anschauen könntet. Vielleicht gibt es ja doch eine einfache Lösung für mich. Ich bin selbst noch Anfänger, wie ihr sicher gemerkt habt. Und von Neuem beginnen, gibt der Zeitplan eigentlich nicht her...
