Scroll through one Tag with Previous&Nextlink

Hey there!

I want to ask about the following:

I have a photoblog, every post contains one picture. Every post is also in one category and has a number of tags (www.konstantin-volke.de)…

When someone clicks a tag all posts with that one tag are listed (with the archive.php). What I want to achieve is that if a user clicks on one of these posts, the previous and next link should only connect posts with that one tag.

At the moment I am using the template tag “previous_post_link(‘%link’, ‘[img-link]’, TRUE);” for this kind of navigation for a post in a category. So is it possible, to inherit a tag and create a “set” for that tag?

I would appreciate every kind of advice.
Enjoy your weekends,

Konstantin
