You can use your own logo in the lower left-hand corner of the Presenter ’09 player. Your custom logo needs to be a Flash .SWF file and you can optionally add your own website link to your logo.
If you’re simply looking to remove the Articulate logo in the lower left-hand corner (and not replace it), refer to the section on "Display powered-by logo" in Player Templates -> Player Controls.
If you’d like to display your own logo in the upper left-hand corner, refer to Presentation Options -> Logos.
To use your own logo in the lower left-hand corner of the Articulate Player:
<poweredbypanel> <enabled>true</enabled> <file>custom_logo_name.swf</file> </poweredbypanel>
Note: Your logo can be up to 42 pixels high. There is no width limitation. However, if it is very wide, it will overlap the player controls.
