FAQ有：

当然可以，用BLOB类型
存放：
<?php
// 如果提交了表单，代码将被执行:

if ($submit) {

// 连接到数据库
// (你可能需要调整主机名，用户名和密码)

MYSQL_CONNECT( "localhost", "root", "password");
mysql_select_db( "binary_data");

$data = addslashes(fread(fopen($form_data, "r"), filesize($form_data)));

$result=MYSQL_QUERY( "INSERT INTO binary_data (description,bin_data,filename,filesize,filetype) ".
"VALUES ('$form_description','$data','$form_data_name','$form_data_size','$form_data_type')");

$id= mysql_insert_id();
print "<p>This file has the following Database ID: <b>$id</b>";

MYSQL_CLOSE();

} else {

// 否则显示储存新数据的表单
?>

<form method="post" action=" <?php echo $PHP_SELF; ?>" enctype="multipart/form-data">
File Description:<br>
<input type="text" name="form_description" size="40">
<INPUT TYPE="hidden" name="MAX_FILE_SIZE" value="1000000">
<br>File to upload/store in database:<br>
<input type="file" name="form_data" size="40">
<p><input type="submit" name="submit" value="submit">
</form>

<?php

}

?>

</BODY>
</HTML>
读取：
<?php

// getdata.php3 - by Florian Dittmer <[e-mail]>
// 调用方法: getdata.php3?id=<id>

if($id) {

// 你可能需要调整主机名，用户名和密码:
@MYSQL_CONNECT( "localhost", "root", "password");

@mysql_select_db( "binary_data");

$query = "select bin_data,filetype from binary_data where id=$id";
$result = @MYSQL_QUERY($query);

$data = @MYSQL_RESULT($result,0, "bin_data");
$type = @MYSQL_RESULT($result,0, "filetype");

Header( "Content-type: $type");
echo $data;

};
?>

---------------------------------------------------------------

可以这样建表
create table images(image_id int not null primary key,
image_data blob
);
---------------------------------------------------------------

注意：blob类型最大可存储64k的图象，超过时可用longblob类型
