When you are ready to send the file you can use Package for Sharing found under the File menu option on the toolbar. 

This will combine your timeline file (*.tlm3 or *.tlmp) with all linked files and package it in a TLMZ file


This TLMZ file can then be opened with either Timeline Maker, the free Timeline Maker Viewer.  

The charts may also be viewed in Powerpoint, via the Timeline Maker menu there. At least the Viewer has to have been installed on that computer.  All events will show your links on the Interactive charts..
