创建表从文件系统插入图像到blob（如何）

Question

当我创建我的表时，我知道如何将数据插入字段，但我不知道如何从我的文件系统中将图像插入blob。

$sqlCommand = "INSERT INTO pages (page_title,page_body,links,thumbs) VALUES
               ('Flash Gallery','Use Actionscript to build a Flash Photo gallery','http://www.google.com','what do i put here????'),
              ('Flash Website','Learn to create a full flash website template','http://www.google.com','what do i put here????'),
              ('XML RSS FEED','Learn to assemble XML RSS Feeds for your website','www.google.com','what do i put here????')";
