Thank you for approaching us.
I am providing you a script below. Please run this script with your database and try capturing screenshots via gtrack again. This time it must solve the issue.
DROP TABLE IF EXISTS `pn_gtrack_image`;
/*!40101 SET @saved_cs_client = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `pn_gtrack_image` (
`IMAGE_ID` int(11) NOT NULL AUTO_INCREMENT,
`USER_ID` int(11) DEFAULT NULL,
`ADD_TIME` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
`IMAGE_FLAG` int(1) DEFAULT '0',
`PROJECT_ID` int(11) DEFAULT NULL,
`TASK_ID` int(11) DEFAULT NULL,
`BLOG_ID` int(11) DEFAULT NULL,
`KEY_COUNT` bigint(20) DEFAULT '0',
PRIMARY KEY (`IMAGE_ID`)
) AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
/*!40101 SET character_set_client = @saved_cs_client */;
