Code to display multiple images using .tpl.php file in drupal 7 I use the following code to render the image from the template file. This code is used when the image name is known. Multiple images can be displayed by adding the same lines of code with different image names. 

global $base_path;
print "&lt;img src='" . $base_path . path_to_theme() . "/../../../default/files/styles/thumbnail/public/xyz.jpg' width='100' height='100' /&gt;";


Is it possible to render the multiple images from the content type with the field name created but without changing anything in the template file every time we upload the image?
If you have multiple images from the content type, and you want to render them. The .tpl.php file must have $node variable and in that variable you will have the image path and image uri for each image with field name, which you want to render. Just save the image path or image uri of image in some variable and do as following:

$img_uri = &lt;image uri path here&gt;;
$image_url = file_create_url($img_uri);
print '&lt;img src="' . $image_url . '" width="100" height="100" alt="style image" /&gt;';


In case your are using Image Styles then you will need to get the image's url and style name and use it like this:

$style_name = &lt;image style name&gt;;
$file_path = &lt;image file path&gt;;
$image_url = image_style_url($style_name, $path);
print '&lt;img src="' . $image_url . '" width="100" height="100" alt="style image" /&gt;';


And I can see that are using Image Style in which your path is something like:

 /../../../default/files/styles/thumbnail/public/xyz.jpg


The rest I think that once you get different image file paths then you can easily loop them as you like.
