Just few more details：
- Add mysql field
`image` blob
- Get data from image
$image = addslashes(file_get_contents($_FILES['image']['tmp_name']));
- Insert image data into db
$sql = "INSERT INTO `product_images` (`id`, `image`) VALUES ('1', '{$image}')";
- Show image to the web
<img src="data:image/png;base64,'.base64_encode($row['image']).'">
- End

Firstly, you should check if your image column is BLOB type!

I don't know anything about your SQL table, but if I'll try to make my own as an example.

We got fields id (int), image (blob) and image_name (varchar(64)).

So the code should look like this (assume ID is always '1' and let's use this mysql_query):
```
$image = addslashes(file_get_contents($_FILES['image']['tmp_name'])); //SQL Injection defence!
$image_name = addslashes($_FILES['image']['name']);
$sql = "INSERT INTO `product_images` (`id`, `image`, `image_name`) VALUES ('1', '{$image}', '{$image_name}')";
if (!mysql_query($sql)) { // Error handling
    echo "Something went wrong! :("; 
}
```
You are doing it wrong in many ways. Don't use mysql functions - they are deprecated! Use PDO or MySQLi. You should also think about storing files locations on disk. Using MySQL for storing images is thought to be Bad Idea™. Handling SQL table with big data like images can be problematic.

Also your HTML form is out of standards. It should look like this:
```
<form action="insert_product.php" method="POST" enctype="multipart/form-data">
    <label>File: </label><input type="file" name="image" />
    <input type="submit" />
</form>
```
Sidenote:

When dealing with files and storing them as a BLOB, the data must be escaped using mysql_real_escape_string(), otherwise it will result in a syntax error.

This is the perfect code for uploading and displaying image through MySQL database.

<html>
<body>
<form method="post" enctype="multipart/form-data">
<input type="file" name="image"/>
<input type="submit" name="submit" value="Upload"/>
</form>
<?php
    if(isset($_POST['submit']))
    {
     if(getimagesize($_FILES['image']['tmp_name'])==FALSE)
     {
        echo " error ";
     }
     else
     {
        $image = $_FILES['image']['tmp_name'];
        $image = addslashes(file_get_contents($image));
        saveimage($image);
     }
    }
    function saveimage($image)
    {
        $dbcon=mysqli_connect('localhost','root','','dbname');
        $qry="insert into tablename (name) values ('$image')";
        $result=mysqli_query($dbcon,$qry);
        if($result)
        {
            echo " <br/>Image uploaded.";
            header('location:urlofpage.php');
        }
        else
        {
            echo " error ";
        }
    }
?>
</body>
</html>
