Skal ha bildefremvisning på siden min. Men til nå har jeg ikke funnet noe jeg er fornøyd med. Og håper noen kan hjelpe meg.

Kriteriene er:

 

Være raskt, og enkelt.

Skal kunne integreres i siden min.(ingen popup side) Og skal ikke åpne ett nytt uavhengig område.

 

Kommer ikke på mer :shrug:

 

Håper noen kan komme med bra forslag :mrgreen:

 

Takker

OK, dette er løsningen vi bruker på [url="http://www.klubblan.net/index.php?side=showimages"]Klubblan.net[/url].




Altså: Showimages.htm inkluderes i index.php (som er hovedsiden/"malen")


Showimages.htm ser slik ut:

Scriptet heter egentlig PHP Sanctum Gallery. Og det gjør det nå og forskjåvidt. Men jeg har moddet det ganske kraftig, blant annet oversatt, gjort om på mye struktur og design ++

Bildene legger du i bilder/. Du kan, og det er meningen at du skal gjøre det, legge bildene i mapper under bilder/. Bildene blir da arrangert i "gallerier" etter navnet på den mappa de ligger i.

Husk å CHMODde mappene. Endret av Mikka
