Image credit for feature images.

## Nonintrusive Image Credits (for feature images). 

Sometimes the feature images come from somewhere else. And we should give credit to those people. The Credit tag shows up to the bottom left of the image. 

1) Update the front matter in your post like so .. 
 ```   
image:
   feature: blah-blah.jpg
   creditlink: http://www.coolsitewithCCimages.com
    credit: Name Of Site
```
2) You can modify the credit styling in main.css
