Hi all, first post here. I'm just starting with Wordpress and am experiencing a small issue. I want to create and use a child theme. I followed the steps for creating a child theme (http://codex.wordpress.org/Child_Themes). The child theme was created and it appears as an option on my Themes page, and it can be applied without issue. But unlike the other Themes on the page (including its parent), there is no preview. The other themes ("Twenty Twelve," "Twenty Thirteen," and "Twenty Fourteen") are all listed with an image preview. My child theme ("Twenty Fourteen Child") does not have any image. This issue arises when I create child themes from other themes as well. Anyone know why this is happening or if I can resolve? Thanks in advance.
