Hopefully someone is able to help me with this. I'm finding my ignorance knows no bounds.
This is my site: gtsb
I have my site set up with the homepage displaying excerpts of the most recent posts. I would like an image to show up with that excerpt (if there is one present in the post). I would also like that image to be full width. I have a screen shot here: http://www.filedropper.com/screenshot2012-04-03at125629pm that I uploaded to filedropper. I am currently using a function called Catch That Image that I found at wprecipes.com. It sort of does what I want. But I'm unsure how to control the image so I can make the width fill the full space. Not sure if this is the best method and if I can adjust it to do what I want. This avoids using custom fields (however i'd use that method as well if i knew how to). I've heard a lot about using custom fields and a few other methods, but have not been able to figure them out either.
If someone can lead me in the right direction i would appreciate it
