Image Galleries & Leaking Pagerank

[dirkla]

I have a website in a niche that's highly graphical in nature. Most of the pages that I rank well for are mainly textual at the moment, but I'm gradually adding image galleries to these pages. The galleries consist of a number of thumbnails that are html linked to the large version of the image (via the Lightbox script). My question: will the page lose pagerank because of the many links from the thumbnails to the images (upto 30/page besides the normal links)?

PR juice is likely to be leaked through any do-follow links, I would recommend adding rel="nofollow" attribute to the linked images.

If its a Lightbox script you might have to hack the source code a little but should be easy enough to find the code which generates the link.

Thanks Danny.

That would mean though that I would lose traffic from Google images.  Can you think of a way to have an image gallery without html links?  If I would use Javascript links, Google wouldn't find the big images either....
