    Greetings,

    I am currently running into an issue with phpThumb throwing PHP errors when trying to generate thumbnails on Front-end or Hover over Back-end image files where they contain capitalized characters (lowercase and numerics do not cause issue).

    Error is as follows:
    [2014-06-23 13:40:31] (ERROR @ /connectors/system/phpthumb.php) phpThumb was unable to generate a thumbnail for: /path/to/httpdocs/core/cache/phpthumb/img-file.jpeg
    [2014-06-23 13:40:31] (ERROR @ /connectors/system/phpthumb.php) Error outputting thumbnail:
    OutputThumbnail() failed because !is_resource($this->gdimg_output) in file "phpthumb.class.php" on line 578
    [2014-06-23 13:40:32] (ERROR @ /connectors/system/phpthumb.php) phpThumb was unable to generate a thumbnail for: /path/to/httpdocs/core/cache/phpthumb/img-file.jpeg
    [2014-06-23 13:40:32] (ERROR @ /connectors/system/phpthumb.php) Error outputting thumbnail:
    OutputThumbnail() failed because !is_resource($this->gdimg_output) in file "phpthumb.class.php" on line 578


    In an attempt to remedy the issue, the site was upgraded from 2.2.10-pl to 2.2.14-pl on the server and a clean .htaccess file was used to verify it was not a Mod Rewrite issue as well.
    List of Addons:

    • FormIt
    • getResourceField
    • getResources
    • MultiUploadDialog
    • TinyMCE
    • Wayfinder

    Any guidance or suggestions would be greatly appreciated. This is the first time running into the issue presented.

    Thanks.
