W3C alist.mod4 Hilfe bei Erweiterung für TN in grau für over

Benki · Beitrag von **Benki** » Do 3. Nov 2005, 15:10

Moin,

ich benutze das Modul w3concepts.alist.mod4.v1 in abgewandelter Form für die Navigation. Es werden nur die generierten Thumbnails angezeigt, die dann zu den einzelnen Artikeln verweisen.

Ich brauche nun Hilfe um folgende Funktionen zu erweitern:

- neben der Erstellung des 'normalen' Thumbnails soll zusätzlich ein Thumbnail von dem gleichen Bild erstellt werden, nur als Graustufenbild

- Bei der Darstellung soll das Graustufenbild angezeigt werden und bei MouseOver soll das farbige normale TN angezeigt werden

Ich habe bereits eine Funktion der GDLib gefunden:

Code: Alles auswählen

imagefilter($image, IMG_FILTER_GRAYSCALE);

Aber meine PHP und SQL-Kenntnisse reichen noch bei Weitem nicht aus, das Modul um diese Funktion zu erweitern.

Kann mir Jemand weiterhelfen?

hier mein derzeitig genutztes Modul:

Code: Alles auswählen

ob dir da einer auf die schnelle antworten wird, wage ich zu bezweifeln...
ist mehr arbeit als 5 minuten code hacken... geschweige denn, dass derjenige sich mit den gd library funktionen doch etwas auskennen muss...
