Creating multiple image crops with each instance of an image upload
You are using imagecache. Here you can create different type of image styles. And you can use below code for display multiple images of various sizes of an original uploaded image.

 $style = 'thumbnail_200_by_200';
 $image_uri = 'public://image_name.jpg';
 $img_url = image_style_url($style, $image_uri);

 &lt;img src="&lt;?php echo $img_url;?&gt;"/&gt;
