Snapshot Theme from WooThemes — empty 'alt' attribute

Question

I´m using Snapshot theme from WooThemes.

The code which resizes (width and height and size in kb), and shows the images (an 'a' tag, wrapping an 'img' tag) is this one:

<?php if ( get_option('woo_resize') ) { woo_get_image('image','210','280');?> 

The problem is:

I´ve setted the 'alt' text while posting and, when trying to see the post image source code, the 'alt' attribute, appears, empty.

Does anyone has passed for this before?

Any tips?

The post which I wanted to have the 'alt' attribute is the first product in the first row, in the first column:

http://kevingstongramado.p.ht/catalogo/?cat=28

I´ve tried to insert code manually, without the use of the theme´s functions..

Here´s what I´ve tried:

EDIT (I´ve noticed posting one new post, that the code doesn´t resize in kb):

<?php $img_attr = wp_get_attachment_image_src($attachment->ID, 'image');
$image = wp_get_image_editor($img_attr[0] ); // Return an implementation that   
//extends <tt>WP_Image_Editor</tt>
if ( ! is_wp_error( $image ) ) {
$image->resize(210, 280, true );
$image->save($img_attr[0]);
}
$alt = get_post_meta($attachment->ID, '_wp_attachment_image_alt', true);            
?>
<a href="<?php echo get_permalink($post->ID); ?>" title="View <?php the_title(); ?>">    
<img src="<?php echo get_post_meta($post->ID, "image", $single = true); ?>" alt="<?php 
echo $alt;?>"/></a>

The code doesn´t resize in kb and, still don´t get the 'alt' attribute.

I´ve tried using 'SEO Friendly Images' plugin. Doesn´t work for me.

What should I do?

Since the original theme demo image doesn't have any value in alt, I'm assuming there is a bug in the theme you might need to open a ticket for: http://demo.woothemes.com/snapshot/

I don't recommend altering original theme template functions but if you are very far into the project and rather not switch out to another theme, I can suggest few things you can try.

In admin-functions.php of the theme, I'd run var_dump($variable_name); where it relates to the function to see where exactly things get wrong. For example, maybe the thumbnail ID variable is null when trying to retrieve the alt text, and therefore returns the empty string. For example, $thumb_id is used as ID of where function grab the alt text:

if ($alt == '') $alt = esc_attr( get_post_meta($thumb_id, '_wp_attachment_image_alt', true) );

So you run var_dump($thumb_id); right before to see if it even holds the right value. If not, then you can trace where $thumb_id comes from and you can find:

$thumb_id = esc_html( get_post_meta($id,'_thumbnail_id',true) );

And you can var_dump($id); here to see if this one holds the right value. If not, then maybe this $id has been wrong since the beginning:

$id = $post->ID;

Then maybe you can try different method to get post ID such as

$id = get_the_ID();

I hope this will at least help you troubleshoot where the problem occurs in Snapshot and substitute the part with better code or point the problem out to WooThemes for faster support.
