Convert HTML to image in php

I want to make a some step of saving data into DB as BLOB data type. I need convert data to BLOB in the DB. I have the data that are considered as HTML output in the some file. The selected programming language is PHP with Zend Framework 1 and database is MySQL.
I tried to save HTML page as valid BLOB image in DB, but it is still not working. I can't find any solutions about it and I don't know how to do. When I got a content from URL and saved it into DB as BLOB by using function file_get_contents($url), that is worked to me fine.
Here is a code that saves the content of the HTML page in the file described below into DB as BLOB.
$file = "C:\test.html";
$fp = fopen($file, 'r');
$content = fread($fp, filesize($file));
fclose($fp);
$dbModel = new MyTable($this->db);
$dbRowSet = $dbModel->find(1);
$dbRow = $dbRowSet->current();
$dbRow->map = $content;
$dbRow->save();
Here is a preview of saved HTML page in DB, but there I can't show any BLOB image.
There is shown BLOB image. I had the URL page and tried to save it into DB.
I expected that the result of saving data (HTML page) into DB should be that DB contains valid BLOB images.
Thank you for your help.

You can download wkhtmltoimage from this link. There is a version for all operating systems so that shouldn't be a problem. Then you can use it like so:
$path="wkhtmltoimg/wkhtmltoimage.exe"; //path to your executable
$url="http://google.com";
$output_path="test.png";
shell_exec("$path $url $output_path");
One thing you want to note is that if PHP is in safe mode, shell_exec will not work and you won't be able to do your conversion.

After this you just need file_get_contents() and save blob in the database.
