Advanced Custom Fields wordpress image size - wordpress

Question

I'm creating a website with a carousel. To load images, I'm using Advanced Custom Fields on Wordpress.
Here is my code :
<?php $images = get_field('slides', $post->ID);
// clean_print_r($images);
if (!empty($images)) :
?>
<div class="wide-container">
<div id="slides">
<ul class="slides-container">
<?php for($i = 0; $i < count($images); $i++): ?>
<!-- slides -->
<li>
<img src="<?php echo $images[$i]['img_slide']['sizes']['large'] ?>" alt="" />
</li>
<?php endfor; ?>
</ul>
</div>
</div>
<?php endif; ?>
I can load images, but they are sized at 1024px wide:
<img src="http://example.com/wp-content/uploads/2013/09/bg_header03-1024x341.jpg" ... />
Is there any way to get full sized images? I've tried to replace :
['img_slide']['sizes']['large']
with
['img_slide']['sizes']['full']
But that doesn't work, and no images are loaded.
In ACF I call image attachment by ID, and it's a repeater field.

Answer 1

Im not sure how do it with return IDs but if you return URL instead you get the full image.
Edit:
Ok I did some test with the Image ID instead, looks like you've confused your array handling somehow. This works for a single image: Should be easy to adapt to your repeater though.
$attachment_id = get_field('slide');
$size = "full";
$image = wp_get_attachment_image_src( $attachment_id, $size );
echo '<img src="' . $image[0] . '">';
//OR
$image = wp_get_attachment_image( $attachment_id, $size );
echo $image[0];

Answer 2

My previous answer was about return: image ID, as specified by the thread starter but now i realize that he was actually talking about return: object.
/*
* Return value = Object
* requires ACF 3.3.7+
*/
$image = get_field('image');
var_dump($image);
/*
Data returned will look like this:
Array
(
[id] => 540
[alt] => A Movie
[title] => Movie Poster: UP
[caption] => sweet image
[description] => a man and a baloon
[url] => http://localhost:8888/acf/wp-content/uploads/2012/05/up.jpg
[sizes] => Array
(
[thumbnail] => http://localhost:8888/acf/wp-content/uploads/2012/05/up-150x150.jpg
[medium] => http://localhost:8888/acf/wp-content/uploads/2012/05/up-300x119.jpg
[large] => http://localhost:8888/acf/wp-content/uploads/2012/05/up.jpg
[post-thumbnail] => http://localhost:8888/acf/wp-content/uploads/2012/05/up.jpg
[large-feature] => http://localhost:8888/acf/wp-content/uploads/2012/05/up.jpg
[small-feature] => http://localhost:8888/acf/wp-content/uploads/2012/05/up-500x199.jpg
)
)

So apparently the original image is not a size but the URL, therefore change:
['img_slide']['sizes']['large']
to
['img_slide']['url']
and you should be fine
