Markr adds a watermark and copyright statement to a webmap. This could be to enable you to comply with licensing requirements of a specific data supplier (for example the Ordnance Survey in the UK).

You can watermark any webmap and choose any image to create a watermark from. You can also add a custom copyright statement that you would like added to your webmap.

All you will need is a webmap (containing the basemap layer) and a watermark image available in the My Content area of your ArcGIS Online account.
