Using Alt text instead of Title text in colorbox

If the title is empty Colorbox will use the alt instead. If you always want to use the alt you can implement theme_colorbox_imagefield() in your themes template.php file.

Copy theme_colorbox_imagefield() from the colorbox.theme.inc file and change

'title' => $variables['title'],

to

'title' => $variables['alt'],

Remember to clea the Drupal cache so it will pick up the new theme override.

Not tested, this but it should work.

My bad, $variables['image']['alt'] it should be.

Images placed with the insert module uses separate functions.

Copy the "colorbox-insert-image.tpl.php" file to your own theme and where it says title="__title__" change it to title="__alt__".

@animelion, did you clear the Drupal cache after you placed a copy of "colorbox-insert-image.tpl.php" file in your own theme?

The problem with editing the original file is that it will be overwritten next time you update the Colorbox module.

It does work, I just tested it. There is catch however that I had not considered before.

I guess you are using the default admin theme "Seven"? When you add/edit nodes your are using the admin theme so Drupal is looking there for template files.

So adding a copy of "colorbox-insert-image.tpl.php" to "/themes/seven" work but that may also easily get deleted next time you update Drupal core.

The insert module itself must have the same problem, I see if there are any talk there how to solve this.

Has this changed in more recent releases of colorbox? I tried following the instructions of overriding the , but couldn't get it to work (no errors or anything, just didn't have any impact). Also, just for testing, I went into the colorbox.theme.inc code and changed the caption section to read

if (!empty($image['alt'])) {
  $caption = $image['alt'];
}

Surprisingly, that didn't have any effect either.

Any help would be much appreciated. The case | switch that I removed when I put that code in there made it seem like there was an option I could select case 'alt' somehow, rather than case 'auto', but I could be totally off here.

switch ($settings['colorbox_caption']) {
	 case 'auto':
		// If the title is empty use alt or the node title in that order.
		if (!empty($image['title'])) {
			$caption = $image['title'];
		}
		elseif (!empty($image['alt'])) {
			$caption = $image['alt'];
		}
		elseif (!empty($node->title)) {
			$caption = $node->title;
		}
		else {
			$caption = '';
		}
		break;
	case 'title':
		$caption = $image['title'];
		break;
	case 'alt':
		$caption = $image['alt'];
		break;
	case 'node_title':
		$caption = $node->title;
		break;
	case 'custom':
		$caption = token_replace($settings['colorbox_caption_custom'], array('node' => $node));
		break;
	default:
		$caption = '';
}

If we render a field and "auto" is used we are using ALT if there is not TITLE. Insert should follow the same logics like a field. Aside of this I have now hundreds of images in wysiwyg content without an title defined. Can we read the alt from the image via JS, please?
