Ich denke, das wird wohl an den Einstellungen in der Datei phpThumb.config.php liegen.
Was muss ich denn verändern, damit es funktioniert oder was läuft da falsch???
Was ich da nicht so ganz verstanden habe, ist die Installation von ImageMagick auf dem Server zwingend erforderlich oder läuft das Erstellen der Thumbnails auch die ImageMagick???
Hier ist der code:
PHP-Code:
// maximum number of pixels in source image to attempt to process entire image.
// If this is zero then no limit on source image dimensions.
// If this is nonzero then this is the maximum number of pixels the source image
// can have to be processed normally, otherwise the embedded EXIF thumbnail will
// be used (if available) or an "image too large" notice will be displayed.
// This is to be used for large source images (> 1600x1200) and low PHP memory
// limits. If PHP runs out of memory the script will usually just die with no output.
// To calculate this number, multiply the dimensions of the largest image
// you can process with your memory limitation (e.g. 1600 * 1200 = 1920000)
// As a general guideline, this number will be about 20% of your PHP memory
// configuration, so 8M = 1,677,722; 16M = 3,355,443; 32M = 6,710,886; etc.
if (phpthumb_functions::version_compare_replacement(phpversion(), '4.3.2', '>=') && !defined('memory_get_usage') && !@ini_get('memory_limit')) {
// memory_get_usage() will only be defined if your PHP is compiled with the --enable-memory-limit configuration option.
$PHPTHUMB_CONFIG['max_source_pixels'] = 0; // no memory limit
} else {
// calculate default max_source_pixels as 20% of memory limit configuration
$PHPTHUMB_CONFIG['max_source_pixels'] = round(max(intval(ini_get('memory_limit')), intval(get_cfg_var('memory_limit'))) * 1048576 * 0.20);
//$PHPTHUMB_CONFIG['max_source_pixels'] = 0; // no memory limit
//$PHPTHUMB_CONFIG['max_source_pixels'] = 1920000; // allow 1600x1200 images (2Mpx), no larger (about 10MB memory required)
//$PHPTHUMB_CONFIG['max_source_pixels'] = 3355443; // 16MB memory limit
//$PHPTHUMB_CONFIG['max_source_pixels'] = 3871488; // allow 2272x1704 images (4Mpx), no larger (about 16MB memory required)
}
// ImageMagick configuration
// If source image is larger than available memory limits as defined above in
// 'max_source_pixels' AND ImageMagick's "convert" program is available, phpThumb()
// will call ImageMagick to perform the thumbnailing of the source image to bypass
// the memory limitation. Leaving the value as NULL will cause phpThumb() to
// attempt to detect ImageMagick's presence with `which`

//$PHPTHUMB_CONFIG['imagemagick_path'] = '/usr/local/bin/convert';
$PHPTHUMB_CONFIG['imagemagick_path'] = null;
}
$PHPTHUMB_CONFIG['prefer_imagemagick'] = false; // If true, use ImageMagick to resize thumbnails if possible; if false only use ImageMagick if PHP memory limit is too low.
// * Default output configuration:

$PHPTHUMB_CONFIG['use_exif_thumbnail_for_speed'] = false; // If true, and EXIF thumbnail is available, and is larger or equal to output image dimensions, use EXIF thumbnail rather than actual source image for generating thumbnail. Benefit is only speed, avoiding resizing large image.
