ImageMagick is unavailable and phpThumb() does not support TIFF source images without it

Dobrý den,

Na stránky ad-atelier.cz mám udělanou galerii v plogger. Teď se mi stalo, že když přidam nový projekt a vložím obrázek, tak je vše vpořádku, ale když dám další obrázek, tak se udělá chyba :Failed: setSourceFilename(/data/web/virtuals/166389/virtual/www/galerie/plog-content/images/projekty-ad-atelier/n__vrh-vstupu—autobusov__-n__dra____-v-__esk__m-krumlov__/2.jpg) set $this->sourceFilename to „/data/web/virtuals/166389/virtual/www/galerie/plog-content/images/projekty-ad-atelier/n__vrh-vstupu—autobusov__-n__dra____-v-__esk__m-krumlov__/2.jpg“ in file „phpthumb.class.php“ on line 214 $AvailableImageOutputFormats = array(text;wbmp;gif;png;jpeg) in file „phpthumb.class.php“ on line 630 $this->thumbnailFormat set to $this->config_output_format „jpeg“ in file „phpthumb.class.php“ on line 640 $this->thumbnailQuality set to „75“ in file „phpthumb.class.php“ on line 657 $this->sourceFilename set to „/data/web/virtuals/166389/virtual/www/galerie/plog-content/images/projekty-ad-atelier/n__vrh-vstupu—autobusov__-n__dra____-v-__esk__m-krumlov__/2.jpg“ in file „phpthumb.class.php“ on line 581 $this->config_cache_directory () is not a directory in file „phpthumb.class.php“ on line 698 SetCacheFilename() failed because $this->config_cache_directory is empty in file „phpthumb.class.php“ on line 2009 EXIF thumbnail extraction: (size=0; type=; x) in file „phpthumb.class.php“ on line 1949 starting SourceImageToGD() in file „phpthumb.class.php“ on line 2095 Not using EXIF thumbnail data because $this->config_use_exif_thumbnail_for_speed is FALSE in file „phpthumb.class.php“ on line 2098 No built-in image creation function for image type „7“ ($this->getimagesizeinfo[2]) in file „phpthumb.class.php“ on line 2187 Populating $this->rawImageData and attempting ImageCreateFromStringReplacement() in file „phpthumb.class.php“ on line 2204 $this->gdimg_source is still empty in file „phpthumb.class.php“ on line 2227 ImageMagickThumbnailToGD() aborting because cannot find convert in $this->config_imagemagick_path (), and `which convert` returned () in file „phpthumb.class.php“ on line 823 ImageMagickThumbnailToGD() aborting because ImageMagickCommandlineBase() failed in file „phpthumb.class.php“ on line 916 ImageMagickThumbnailToGD() failed in file „phpthumb.class.php“ on line 2236 phpThumb() v1.6.2-200511240855 ImageMagick is unavailable and phpThumb() does not support TIFF source images without it  …. můžete mi pomoci?
