In addition to a basic PHP installation, this component requires certain PHP settings to be setup correctly in order to function optimally.

PHP settings can be changed in php.ini, as described in the PHP documentation

• safe_mode safe_mode must be disabled in order for Expos? to work correctly
• disable_functions The disable_functions directive must not include the functions exec and set_time_limit
• file_uploads file_uploads must be set to On if Expos? is to be able to upload files from your computer
• upload_max_filesize and post_max_size These configuration parameters control the maximum file size that can be uploaded. Adjust these from the default 2M setting to something larger if you have problems uploading pictures from higher resolution cameras.
