Many of my posts are just images so timeline shows loads of code

If you see my use of the timeline here – http://www.accesswalden.com/wenden-road/timeline/

Wherever I have just got an image as a post (newspaper cuttings in my case) – the timeline excerpt shows the image code. Either I want it to pick up an excerpt from somewhere or I want it to not show the code at all.
