Answer 1

You have to create a php file, for example image.php. Inside it you can put something like that:

<?php
   //Your code to call database for image id (from _GET['id']), for instance:
   $image_id = $_GET['id'];
   $data = mysql_query("Select image from images where id = $image_id");

   while($data = mysql_fetch_assoc($query)){ 
      $image=$data['image'];
      header("content-type: image/jpeg");
      echo $image;
   }
?>

Then, in your view, you can do:

<img src="image.php?id=IMAGE_ID" />

将其发送到php上的其他页面，并像这样调用它

<img src="differentpage.php?id=<?php echo id ?>">
