How can I position background image in the center?



I am able to use the image of a diagram of my network rack as a background in Maps. However, it positions the image left of the field. How can I reposition the image so that it appears, for example in the center or where ever I'd like on the field?

I would like to display sensors and graphs on both sides of the rack in a Map.

Hello ginmardo, can you give this a try and let us know the results?:

You'll need to create a new map object with e.g. a status related background.

Go to the folder <PRTG Installation Directory >\webroot\mapobjects and create a new .htm file with the content

<!--Status Icons: Status Related Background-->

<div class="map_object map_icon2 map_icon_large <#sensor type="colorclassofstate" prefix="map_iconcolor_" id="<@objectid>">" id="<@itemid>" objectid="<@objectid>" subid="<@subid>" style="<#mapobject type="coordinates" subid="<@subid>" mode="<@editmode>">">
  <#mapobject type="objectgrip" mode="<@editmode>">
  <#mapobject type="htmlbefore" subid="<@subid>">
  <img src="/images/test.jpg">
  <#mapobject type="htmlafter" subid="<@subid>">

Then copy the image to the folder webroot\images and replace the

img src="/images/test.jpg with the name of the image.

The object will be available in the Map Editor > Status Icons > Status Related Background.

Hey Oscar, it worked.

However, I am gonna nitpick a little: I get a red backdrop behind the image whenever I extend the size of the image border. But, it'll do for now.

Hi homoroje,

There are certain things you can modify on reports but not backgrounds:
