Here’s a nifty trick that just came through my RSS reader. Let’s give credit where it’s due first because I didn’t come up with this! It came through my reader from the WP Snippets site, this post right here. We’re going to grab the first image from the post, and set it as your featured image automagically!

I saw this post from c.bavota of bavotasan.com and I really wanted to work this out. One of my main goals for my new theme is to keep things lightweight, and use css whenever possible. This gave me my opportunity! First you’ll need to check out the link above to see how the idea works. Then we adapt:
One of our VoodooPress readers had a question recently. Seems they were using the front end posting form we started talking about here.

So when I finished up with my twentyeleven child theme, I had an even wider header image than my previous child theme. A while ago we covered how to include featured or attached images in our RSS feed. Well, that technique works great, but it uses the default image size of your theme, whatever that is defined as. With a 1050x175px header image, that looked a bit silly in my feed. So I just adjusted the featured image size by including a specific image for my feed. Check this out!
