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 "<img src='" . $base_path . path_to_theme() . "/../../../default/files/styles/thumbnail/public/xyz.jpg' width='100' height='100' />";
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?
