Extension:YahooMaps

What can this extension do?
This extension allows you to easily create Yahoo maps and markers. The extended descriptions of the markers are all wikitext, enabling links, images, etc. Yahoo maps (unlike Google maps) are allowed to be used for both private (i.e. intranet) and public sites. Additionally, it provides the ability to place a small geocoding tool that will convert addresses to marker descriptions.

Markers "jump" in IE
There is an issue with Yahoo Maps in the default Monobook skin within Internet Explorer! IE has layout issues that Monobook attempts to solve in. Unfortunately, the solution is a bit overzealous, and will cause your map to display incorrectly--it will start out ok, but after about a second all markers will be offset downward by some amount proportional to n-1 (where n is the marker number). To fix this, change the following: to:

Popups have a white background
Having just installed MediaWiki 1.11, I'm noticing that the markers tend to have a boxy, white background that wasn't present in 1.8 (at least they do in Monobook). To solve this, add the following to your wiki's MediaWiki:Common.css:
