В таблицу вообще никаких данных не приходит...
Покажите что вы сделали.
]]>Примерная структура таблицы для хранения картинки:
CREATE TABLE IF NOT EXISTS `file` (
`id` mediumint(8) unsigned NOT NULL auto_increment,
`name` varchar(100) NOT NULL,
`type` varchar(100) NOT NULL,
`size` int(10) unsigned NOT NULL,
`content` mediumblob NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=cp1251;Допустим, вы загрузили картинку через POST форму, значит появится глобальная переменная $_FILE
<form action="" method="post" enctype="multipart/form-data">
<input type="hidden" name="MAX_FILE_SIZE" value="<?php echo (2*1024*1024); ?>">
<input type="file" name="file">
</form>Запись в БД.
