Multiple Clickable text links in Lightbox Descriptor Text

I have a nice Lightbox gallery on my website now, courtesy this great video by  Dan Carr (https://helpx.adobe.com/dreamweaver/how-to/make-web-portfolio.html#). I am wondering if anyone might be able to help me out with making the text in the image descriptor (visible while Lightbox gallery image is on-screen) into clickable links.

Here is sample code from the first gallery image:

<!--INSTRUCTIONS FOR BASIC USE OF LIGHTBOX: http://lokeshdhakar.com/projects/lightbox2/-->
<!--LIGHTBOX IMAGE1-->
<div id="lightboxWrap">
<a href="/images/gallery/highres/HiroshimabendJ10C.png" class="imgGallery" data-lightbox="slideSeries" data-title="ODP066 Hiroshimabend J10C - Available at Discogs">
<div class="thumbnailWrapper"><img src="/images/gallery/preview/HiroshimabendJ10C.png" alt=""/>
</div></a>

I have underlined in bold text the word Discogs, denoting where I would like to put the link inside of the text field for the image descriptor so that when the image is up, if the link is clicked, it will open in a new window.

Simple enough, eh? (at least explaining the concept) I just wouldn't know where to begin on figuring out something like this.

Thanks in advance for any assistance...Cheers then!
