This animated PNG file can be used in the new Steam Library (currently in open beta) that supports the animated PNG file format.
First right click the TAR animated image below and save it. Use the Add Non-Steam Game function in Steam and browse to the TAR Launcher exe (located in the: Empire Total War\data\TAR\Launcher folder) to add a TAR Launcher shortcut to Steam. Then right click it and go to > Manage > Set Custom Art Work. Now browse the TAR animated image to add it.
And you're done! Enjoy!
