Below is the text coming from SEM Rush when it finds a Simple Image Gallery, seems like they want <IMG> tags and not <a href> tags that point to the image.  

Is there any workaround for this, a different skin we can be using, or is it the nature of using a lightbox in general?

Thanks,

ABOUT THIS ISSUE
We detected that some links to resources are formatted with <a href> HTML element. An <a> tag with a href attribute is used to link to other webpages and must only contain a page URL. Search engines will crawl your site from page to page by following these HTML page links. When following a page link that contains a resource, for example, an image, the returned page will not contain anything except an image. This may confuse search engines and will indicate that your site has poor architecture.

HOW TO FIX IT
Review your links. Replace <a href> links with tags necessary for specific resources. For example, if you’d like to add an image, use an <img> tag with an alt attribute describing the contents of your image.
