I've been trying to work a solution to this for a while. I am trying to insert post thumbnails into my website, much like this, beside my post excerpts on my homepage and search results page: http://i39.tinypic.com/35l56l1.png (screenshot from http://www.simplyshredded.com)
I'm currently using a fairly lightly edited version of the scarlett theme (as is simplyshredded), and I'm unsure how to approach this problem. I've implemented featured images on every single post, and installed timthumb, as well as adding code that was supposedly missing in the theme, that was made pre-2.9, in order to activate thumbnails to no avail. My website is http://www.muscleinsight.com, if you need to examine my site layout.
All help is greatly appreciated :)
