Ich habe irgendwann irgendwo das Modul Picture gefunden und erfolgreich eingebunden. Ich verwende auf einer Seite mehrmals dieses Modul. Und möchte zulassen jedem Bild eigene Größe eingeben, was mir natürlich nicht gelingt.
Das ist mein Intput:

?>Wie könnte ich die eingegebenen Höhe und Breite korrekt zu jedem Bild zuordnen ( nicht überschreiben) und die entsprechenden Berechnungen durchführen. Jetzt ist es so, dass die Eingaben nur vom ersten Bild verwendet werden, da ja auch nur die Platzhalter CMS_VALUE[1] und CMS_VALUE[2] zur Verfügung stehen.
Danke für Tipps
