Currently the available options for "Caption" under the display options for Colorbox are "Automatic, Title text, Alt text, No title, None". Placeholder tokens would allow for ultimate control, e.g. "[node:title] - [node:field-url]". I am aware of the views colorbox trigger field, but this would be a much more practical and simplistic option in my opinion.

Thank you so much, frjo! I applied the patch and it works great.

I have one problem however, as I want to show an actual URL in the caption but the tokens are stripped of all HTML.

For example, currently it will output something like this:

<a rel="gallery-21" class="..." title="Test - link" href="...">
<img title="" alt="" src="..." />
</a>

I want to output with encoded HTML like this:

<a rel="gallery-21" class="..." title="Test - &lt;a href=&quot;http://www.example.com/&quot;&gt;link&lt;/a&gt;" href="...">
<img title="" alt="" src="..." />
</a>

I had a go at making modifications, but unfortunately I am a bit rusty on the development side so it did not work out. I hope you may be able to help me with this.

@benmalen, I don't believe HTML is allowed inside the title attribute. That’s why Drupal l() function that colorbox use to build link strips it out.

Hmm, I used to use Lightbox and you could use HTML in the caption so I was hoping this could be done with Colorbox.

Can I insert links in the caption?
Yes, but you need to convert quotes and greater and less than symbols into their html entity equivalents. For example:
<a href="images/image-4.jpg" rel="lightbox" title="&lt;a href=&quot;link.html&quot;&gt;my link&lt;/a&gt;">Image</a>

I guess I can make do without. Thanks again.

token_replace() is a core's function, so there's no dependency on token module. Field settings could be stored in-code or provided with features module. Token is useful when you editing setting.

Code should be: 

case 'custom':
  $caption = token_replace($settings['colorbox_caption_custom'], array('node' => $node));
  break;

So, here's a question stemming, I think, from the tokens. I want to create a space for lengthier captions to exist using these tokens... in theory I could do this with title, but it's not long enough. How can I tie something up with each separate image that I could then use the tokens to implement? IE a separate caption field for each image. When Image wasn't tied up with the core in 6, this might have been a bit easier... I'm just hoping I won't have to create a new content type to try and get this to work.
