从数据库检索图像，显示并将其附加到链接

Question

I have Images stored in my DB, I want to retrieve them all and display them in the browser. It works just fine, but I want to give the user the ability to click on the picture so that they can have a better view of the picture (so display it with its original size). I tried many things but didn't work. second question: if I want my code to support multiple images type (such gif, jpg, etc..), if there a way to do it without having to save the image type (when I insert the images) and play with a whole bunch of if/else (when I retrieve them)?
This is my code

  $count = 0;
       echo " <div class=\"row\">"; 
   while($row = $result->fetch_assoc()) {

       $imagename = base64_encode( $row['Image'] );
       if(($count%3) ==0){
        echo "</div>";
         echo " <div class=\"row\">"; 

            echo "  <div class=\"col-sm-2\">";
            echo " <a href=\"$imagename.jpeg\" class=\"thumbnail\">";
            echo '<img src="data:image/jpeg;base64,'.base64_encode( $row['Image'] ).'" style=\"width:130px;height:130px\"/>';
            echo"</a></div>";      


        ++$count;

       }else{
                echo "  <div class=\"col-sm-2\">";
            echo " <a href=\"$imagename.jpeg\" class=\"thumbnail\">";
            echo '<img src="data:image/jpeg;base64,'.base64_encode( $row['Image'] ).'" style=\"width:130px;height:130px\"/>';
            echo"</a></div>";
            ++$count;

       }

   }
 echo "</div>" ;

The answer to your first question is "You have to use light-box jQuery plugin", in order to display larger (original size) of a thumbnail you need to use any lightbox plugin, I recommend using this one http://www.jqueryscript.net/zoom/Responsive-jQuery-Lightbox-Like-Image-Zooming-Plugin-Lighter.html Or you can search for any other plugin, there are thousands of them.

Regarding your second question, If you will use data as an images source, you have to specify a type, no way you can do that without mentioning types.
