Event Calendar post thumbnail logic

/**
 * I'll concentrate on the post thumbnail code here. The other
 * stuff should be left just as Jonah had it.
 *
 * In this first example I am using the default "post-thumbnail"
 * size and I am additionally assigning the "alignleft" CSS class
 * (most themes use this to apply a float:left).
 *
 * I'm also doing a bit of a hack here by specifying the image
 * width (in this case 100px) as an inline style (it's hackish
 * because the width and height are already present in the img
 * tag output, and we're overriding those). So, this should work
 * but arguably isn't ideal.

the_post_thumbnail('post-thumbnail', array(
    'class' => 'alignleft',
    'style' => 'width: 100px'
));


/**
 * A slight improvement would be to add a new CSS class, here I
 * have used "featured-event-thumb" and you would then add additional
 * stylesheet rules to control it's appearance, size etc, something
 * like this:
 *
 *  img.featured-event-thumb {
 *      float: left;
 *      height: 100px;
 *      margin-right: 10px;
 *      width: 100px;
 *  }

the_post_thumbnail('post-thumbnail', array(
    'class' => 'featured-event-thumb',
));


/**
 * One final variation could be to register a new post thumbnail
 * size and use that in place of the default "post-thumbnail"
 * size. Here I have used the notional "event-thumbnail" size.
 *
 * You would specify the target size in the thumbnail registration
 * code, the benefit of this approach being that the image sent
 * to the browser would be the correct size straight off the bat,
 * no wasted bandwidth.
 *
 * If you want to find about more about registering post
 * thumbnail sizes then see the following link.
