# Branding PNG Downloads

Users can download graphs as PNG images. You can apply some branding to this format:

• You can add some text (such as a copyright statement).
• You can specify the filename of the PNG (or choose to have this automatically generated).
• You can specify the size of the PNG (or choose to have this set automatically based on the current size of the user's browser window).

To change these settings, edit <tomcat_home>\webapps\webapi\scripts\sw2-charts\sw2-chart-export-options.js.

See sw2-chart-export-options.js for full details.
