Mir war wichtig, dass dieser Hinweis nicht bei reinen Fotobeiträgen auftaucht – Fotos verlieren schließlich selten an Relevanz. Zuerst habe ich selbst eine funktionierende Version geschrieben, anschließend den Code von einem Sprachmodell noch etwas optimieren lassen.

Mir war wichtig, dass dieser Hinweis nicht bei reinen Fotobeiträgen auftaucht – Fotos verlieren schließlich selten an Relevanz. Zuerst habe ich selbst eine funktionierende Version geschrieben, anschließend den Code von einem Sprachmodell noch etwas optimieren lassen. Jetzt läuft bei mir folgende Variante:
