General Support: Error when uploading images

I get the following error message when I try to upload files:

Failed: $AvailableImageOutputFormats = array(text;wbmp;png;jpeg) in file "phpthumb.class.php" on line 519 $this->thumbnailFormat set to $this->config_output_format "jpeg" in file "phpthumb.class.php" on line 529 $this->thumbnailFormat staying as "jpeg" because "" ($this->f) is not in $AvailableImageOutputFormats in file "phpthumb.class.php" on line 539 $this->thumbnailQuality set to "75" in file "phpthumb.class.php" on line 546 $this->config_cache_directory () is not a directory in file "phpthumb.class.php" on line 587 SetCacheFilename() failed because $this->config_cache_directory is empty in file "phpthumb.class.php" on line 1815 GetImageSize("") failed in file "phpthumb.class.php" on line 1800 starting SourceImageToGD() in file "phpthumb.class.php" on line 1886 Not using EXIF thumbnail data because $this->config_use_exif_thumbnail_for_speed is FALSE in file "phpthumb.class.php" on line 1889 phpThumb() v1.6.0-200507180958 "O:Hosted Web SitesZach.Evanssavageideas_comevansphotos/images/carter's_first_year/first_month/100_0189.jpg" does not exist
