How do I show all the images in my public:/images/ folder?
Firstly get fid of the images and then put it in the function below Like i did:-

$file_load=file_load($fid);  
$url=$file_load-&gt;uri;


$url retrieve you image path where you have uploaded your image.
Like:- public:/images/image_name

Use this fuction to display your image. image_style

$variables= array(
'style_name' =&gt; 'style_name', 
'path' =&gt; $url, 
'getsize' =&gt; FALSE, 
'attributes' =&gt; array(
 'width' =&gt; '100',
 'height' =&gt; '100')
);

echo theme('image_style',$variables);


Note :-if you are using drupal theme('image_style',$variables) function to display image.then put url like public:/images/image_name in path given above.else you are using  to display image then use below code.

Or You can also do this.

$file_url=file_create_url($url); 
echo '&lt;img src="'.$file_url.'"'&gt;;


Hope this will help you.
