[Plugin: Taxonomy Images BETA] Bug report and fix: alt property of images

Hello!

Really enjoying this plugin — solved a major issue for me very elegantly.

One bug report: I’m getting alt=”Array” in my images.

I’m calling:

$img = $taxonomy_images_plugin->get_image_html( 'large', $term->term_taxonomy_id );

and getting back:

<img src="<url-omitted-but-correct>" alt="Array" title="" width="306" height="172" class="alignnone size-large wp-image-25" />

Looks like the culprit is line 327 of taxonomy-images.php:

$alt = get_post_meta( $attachment_id, '_wp_attachment_image_alt' );

According to the codex page, get_post_meta returns an array unless you specific single=true.

Changing the line to set single fixes the problem:

$alt = get_post_meta( $attachment_id, '_wp_attachment_image_alt', true );
