Note: You will need to identify the dimensions of the old map image and resize your new map image to that size before uploading to the Assets page.
To change the map image, upload your new image to the Assets page and then select ‘map image’ from the ‘Select an element to edit’ drop down of the floating tool bar. Notice how only the URL for the image is listed. To replace the map image, you will need to locate the URL of the replacement image you uploaded to the Assets page. There are several ways of getting that URL. One of method is to click on the ‘Image’ button and then click the ‘Asset Manager’ button. Once the Asset Manager window is open, click the ‘Preview’ link to view the replacement map image and copy the URL from the address bar. Now close the Preview window, close the Asset Manager, and close the image properties window. Delete the old map URL from its current location and paste the replacement map URL where the old one was and click the ‘Save site wide changes’ button.
Tip: The PrtScn button on your keyboard captures what you see on your monitor and saves in the clipboard memory.
