Each item in the media bar on the homepage comes from a post. All of these posts are pulled from a single category that is defined within the ePanel theme options. The first thing you need to do is choose which category you would like to pull your posts from. To do this, navigate to the Appearances > Chameleon Theme Options page and click on the General Settings > Homepage tab. Look for the “Exclude categories from homepage media section” section and select, with a green checkmark, which categories you would like to display in the media bar.
Next you will need to add “media” to each of the posts within those categories. To add an image to the media bar, you simply need to add the Thumbnail custom field to each of the posts as outlined in the “Adding Thumbnails Images To Posts” tutorial above.
You can also add video to each of the posts in the media bar. To do this you will need to add a new custom field to the post with a Name of “et_videolink” and a Value of the URL to your video. You can only embed videos from video hosts such as youtube.com or vimeo.com. Once you have chosen a video, simply add the URL to the video in the “Value” field of the custom field. For example, if I wanted to add the following video to the post: http://vimeo.com/21294655 then all I would do is type “http://vimeo.com/21294655” into the Value field of the “et_videolink” custom field.
