ich möchte zu Links auf Webseiten in Contendio die passenden Screenshots als Thumbs einbinden.
Jetzt habe ich im Web (http://www.zubrag.com/scripts/) etwas gefunden, was genau dies verspricht. Nur habe ich jetzt ein Problem, wie binde ich die beiden PHPs so ein, dass es funktioniert...
Würde mich freuen, wenn mir jemand helfen würde!
Die Scripts sind:
webthumb.php

###############################################################
# Website Thumbnail Image Generator 1.1
###############################################################
# Visit http://www.zubrag.com/scripts/ for updates
###############################################################
#
# REQUIREMENTS:
# PHP 4.0.6 and GD 2.0.1 or later
# May not work with GIFs if GD2 library installed on your server
# does not support GIF functions in full
#
# Parameters that can be passed via url (if not passed will be used values which are set below):
# url - url of the target website
# x - max width
# y - max height
# q - quality (applicable only to JPG, 1 to 100, 100 - best)
#
# Sample usage:
# 1. webthumb.php?url=http://www.microsoft.com
# 2. Set maximum thumbnail size to 150
# webthumb.php?url=http://www.thumbnails.com&x=150&y=150
###############################################################
// Folder to save all thumbnails.
// Must end with slash!!!
$thumbnails_folder = 'Z:/home/localhost/www/thumb/cache/';
// thumbnails expiration time in minutes
$cache_expire_time = 60;
// quality (for jpeg only)
$image_quality = 100;
// resulting image type (1 = GIF, 2 = JPG, 3 = PNG)
$image_type = 3;
// maximum thumb side size
$max_x = 100;
$max_y = 100;
// If not equal 0 then cut original image size before resizing (in pixels).
// Long page will have bad thumbnail, its better to cut page length first.
