You pre-configure markers in Map/Note. This is similar to before, but you can control everything from the template now.

Previously someone had to go edit the image maps with a fixed set and carefully configure the many css entries and template, which was non-trivial to say the least.

As it is now:
 * you have a set of names which are allowed, and are at the top of the settings. If the user puts a name that doesn't exist they get the Blip. But you can make the list work any way you want, or even remap known names to new names there over time.
 * there is a section for setting css classes per name. This takes care of everything that was needed for the image map way. This could also be used for marker names that don't have image maps if you wanted but not necessary.
 * There is a section for wiki image file or inline data: image to set the image directly instead of through css above, but could be used in conjunction with the css above.
 * There is a section to define offsets for centering, or other adjustments, otherwise icons get placed by their top left corner on their spot on the map. For the old way this had to be done in css.

Many times a bunch of names will just have one setting, like many images use the same offsets and can be configured with one actual setting in the template together, which makes it much easier.

Basically you can do almost anything for all markers in about 40 lines or so in one template, including all of the wow ones atm. And you have the ability to remap things from that template no matter how many wiki pages call or transclude the Maps infrastructure. This over time ends up being a pretty powerful facility, or was, but now you don't have nearly the requirements as before to change anything. You could even in the adjustments section rescale a overly large marker without re-uploading one, that maybe a user submitted.

All of this also basically holds true for the Map/File template for the maps themselves.
