Just for reference, to post an embedded map of a specific location using Gmap4, (but without a gps trail file) here's how:

1.  First, you need to post using HTML, so you need to change the default "Markup" option (it is just below the text input window when you create a message) from  using UBBCode  to  using HTML and UBBCode.  It should be enabled, but if you can't find this option, send me a PM (click my name on the left).

2.  Copy this code into your post:
<iframe style='width: 800px; height: 600px; margin: 0' frameborder='0' scrolling='no' src=http://www.mappingsupport.com/p/gmap4.php?ll=36.578325,-118.292626&z=14&t=t2></iframe>

Change the "ll=" (Latitude/Longtitude) parameters to match the location you want to display.  Change the "z=" parameter to the zoom level you want. 15 is fully zoomed in, 14 zooms back one notch.

Post your message.

Below is what the code above will display.  You can use this map to find the area you want to display, since it displays the coordinates of both your mouse pointer and the map center.

To find another location, try these steps:
    Zoom out
    Click and drag the map so it shows the area you want
    Zoom in and re-center the map the way you want
    Right-click (at the center) to get a popup of the desired map coordinates
    Copy/paste the "Lat/Lon" map coordinates into your message.





To create a clickable link to the full-screen version, copy/paste the following line into your post:

[url=http://www.mappingsupport.com/p/gmap4.php?ll=36.578325,-118.292626&t=t4&z=14&coord=latlng]full screen version[/url]

You can change the lat/lon params to your area of interest. The "t=" and "z=" can be tweaked to change which map type and zoom-level you want initially.

Here's the result:   full screen version

I sure like this tool!
