I just spend some time to create a slim bookmarklet that enables mapping, geocoding and geotagging directly in your Flickr photo page. It works with all common browsers without the need for any extension.

Don't waste your time: Grab it here!
The bookmarklet uses dynamic scripts. So all future improvements will be available without any worry.

A random collection of my geotagged photos. Click them, to see how the map link could look like:
GeoTagging is the process of adding geographical identification metadata to various media such as websites, RSS feeds, or images. This data usually consists of latitude and longitude coordinates, though it can also include altitude and place names. – Wikipedia
A bookmarklet is a small JavaScript program that can be stored as a URL within a bookmark in most popular web browsers, or within hyperlinks on a web page. Because Internet Explorer uses the term favorites instead of bookmarks, bookmarklets are also less commonly called favlets or favelets. – Wikipedia
Geocoding is the process of assigning geographic identifiers to map features and other data records, such as street addresses. You can also geocode media, for example where a picture was taken, IP Addresses, and anything that has a geographic component. – Wikipedia
