Bilder mit Javascript anzeigen

Beitrag von **schimanski99** » 21.07.2009, 18:55

Liebe Abakus-Gemeinde,
ich suche schon den ganzen Tag nach einem Script, mit dem ich mehrere Bilder (Produkte) nebeneinander anzeigen kann und per Mausklick auf eines der Bilder ein großes Bild angezeigt wird.

Leider beherrsche ich kein Javascipt. Vielleicht kann mir hier jemand helfen?

Danke im Voraus,
Renate

Entweder du suchst dir bei https://www.dynamicdrive.com/dynamicindex4/indexb.html eins aus oder ansonsten habe ich ein Script für dich was zumindest das Bild groß anzeigt.

Hier ein Beispiel (eingedeutscht) wie du jedes deiner Bilder einbinden müsstest:

Code: Alles auswählen

<a href="MeinGrossBild.gif" rel="thumbnail">
 <img src="MeinThumbnail.gif">
</a>

Code: Alles auswählen
