• new JS fkt. showMarkers(map, sym, visible) now you can control the visibility of GPX markers

• bugfix: kml multimap

I’d like to change the size of the map displayed (from 600px to 900px width); but can’t seem to find where to edit that?

• changing the map size is done by style command inside the ShortCode like
  [map style="width:600px; height:900px;"] The style parameter must be css conform.

In full size mode there are some elements on top of my map, how can I hide this?

• Go to the plugins option-settings page and increase the full-size z-index as needed. (since V 1.13)

Full size doesn't use the whole browser screen. What is wrong?

• fixed sice V 2.14.

Google Chrome seems to have problems on full size?

• fixed (since V 1.13)

Is it possible to get several markes into one map?

• Yes, you can use gpx/kml files or google fusion tables

Can I use a marker together with a gpx or kml file inside the same map?

• Yes you can add one additional marker beside a GPX- or KML-file.
  if you need more you can add markers as waypoints inside the gpx file like:
  <wpt lat="51.36162" lon="8.3341" >
<name> put in something here! </name>
<desc> this will be displayd in an Infowindow. </desc>
<link href="http://www.wiki.org/"><text> link text </text></link>
<sym>0</sym>
</wpt>
  The sym tag is used to display one of the images inside the plugins img-directory. <sym>0</sym> will show img/sym_0.png as markerimage.

I have to do translucent polygons. I have a gpx with closed roads but I have no idea how to make them translucent polygons.

• GPX format cannot store areas, use kml or convert it to kml.

Do your plugins allow a frontend user to plot a trail on a map and attach it to an article?

• yes, the Pro-version map editor can plot tracks and waypoints

Where to enter the Google API key?

• The plugin uses the new google V3 API, no key is needed.
