You should be able to do Subtitles by selecting TEXT from the Media Generators. You have to create a separate Video Track and place above everything else (Or at least above your images).
Using the Tabs, you can then select placement, fonts and other properties. Your going to have to use the Keyframe Controller Timeline to determine when and where the subtitles are used.
