Looking to add a link to del.icio.us to my permalinks. Not sure if it's possible to do it on archive pages for each listing...but if so, I'm looking to add that as well.
I've seen this done a bunch of times...where the little four square/color logo appears underneath a post and if you click on it, it asks you if you want to bookmark this post/site.

Any/all help is greatly appreciated.
Thank you.

This plugin does the trick for me.

I see in the comments that this does not include images for each. What did you do to solve the missing images/logos problem?

I appreciate your help!
