* @class UploadHandlerPhoto
* @brief Improved checks and update of database after upload of photos.
*
* This class extends the UploadHandler of the jquery-file-upload library. After
* the upload of a photo we do some checks on the file and if no check fails then
* the Admidio database will be updated. If you want do upload files for the download
* module just create an instance of this class.
* @par Examples
* @code // create object and do upload
* $uploadHandler = new UploadHandlerPhoto(array('upload_dir' => $uploadDir,
* 'upload_url' => $uploadUrl,
* 'image_versions' => array(),
* 'accept_file_types' => '/\.(jpe?g|png)$/i'), true,
* 'array('accept_file_types' => $gL10n->get('PHO_PHOTO_FORMAT_INVALID'))); @endcode
