Pictures of trigger point muscle fascia
You could have easily find these using a simple google search, however I will point several out:


See figure 1 of this article for an ultrasound image of a trigger point. Really interesting!
See figure 1 of this article for a schematic representation, and figure 2 for a real image. Although you did not ask for a deeper understanding of this topic, if you want to read more about it I would recommend reading this paper as it covers a lot of aspects (such as pain signals to the brain).
This article covers different imaging techniques and facilitates interpretation by using arrows to point out the trigger points. 


If this is not what you are looking for please specify what you mean with "pictures"? (vibration sonoelastography, schematic, ultrasound, etc.) I cannot point you in a direction for real life images (if these even exist).
