General Support: Image import error

Hi guys, Ive used plogger several times for friends websites, but this is a new error for me. It runs perfectly but when I try and import photos that have been uploaded the following error shows up:

Failed: setSourceFilename(/home/virtual/site4/fst/var/www/html/galimages/posh_funk/test_2/dsc_0085.JPG) set $this->sourceFilename to "/home/virtual/site4/fst/var/www/html/galimages/posh_funk/test_2/dsc_0085.JPG" in file "phpthumb.class.php" on line 216 $AvailableImageOutputFormats = array(text;wbmp;gif;png;jpeg) in file "phpthumb.class.php" on line 636 $this->thumbnailFormat set to $this->config_output_format "jpeg" in file "phpthumb.class.php" on line 646 $this->thumbnailQuality set to "75" in file "phpthumb.class.php" on line 663 !$this->config_allow_src_above_docroot therefore setting "/home/virtual/site4/fst/var/www/html/galimages/posh_funk/test_2/dsc_0085.JPG" to null in file "phpthumb.class.php" on line 790 $this->sourceFilename set to "" in file "phpthumb.class.php" on line 587 phpThumb() v1.6.2-200511240855 "" does not exist $this->config_cache_directory () is not a directory in file "phpthumb.class.php" on line 704 SetCacheFilename() failed because $this->config_cache_directory is empty in file "phpthumb.class.php" on line 1986 GetImageSize("") failed in file "phpthumb.class.php" on line 1869 using ImageMagick path from `which convert` (/usr/bin/convert) in file "phpthumb.class.php" on line 825 source dimensions set to 100x100 in file "phpthumb.class.php" on line 875 ImageMagick called as (convert -coalesce -geometry 100x100 "" png:/tmp/pThumb0Pu2m3 2>&1) in file "phpthumb.class.php" on line 899 ImageMagick failed with message (convert: unable to open image `': No such file or directory. ) in file "phpthumb.class.php" on line 904 ImageMagickThumbnailToGD() aborting because ImageMagickCommandlineBase() failed in file "phpthumb.class.php" on line 923 ImageMagickThumbnailToGD() failed in file "phpthumb.class.php" on line 1876 EXIF thumbnail extraction: (size=0; type=; x) in file "phpthumb.class.php" on line 1925 starting SourceImageToGD() in file "phpthumb.class.php" on line 2073 Not using EXIF thumbnail data because $this->config_use_exif_thumbnail_for_speed is FALSE in file "phpthumb.class.php" on line 2076 Populating $this->rawImageData and attempting ImageCreateFromStringReplacement() in file "phpthumb.class.php" on line 2182 phpThumb() v1.6.2-200511240855 cannot fopen("") on line 2195 of /home/virtual/site4/fst/var/www/html/lib/phpthumb/phpthumb.class.php
