Which is the child theme and which is the parent theme?

Question

In the themes folder for my blog, there are three folders and one file:

The file is index.php and the folders are: twentyeleven / wordfruit / twentyten

The blog is at http://wordfruit.com/blog

Obviously folders could be given any label, but I think the folders are organised fairly logically.

Question 1: Is 'twentyeleven' likely the child theme and 'wordfruit' likely the parent theme?

Question 2: I want to edit a file so that when a user clicks a thumbnail image in the list of blog posts, the blog post opens up...

(As per this post: How to make thumbnail images click into blog posts )

As I understand, I need to edit the index.php file...

Do I edit the index.php in the child theme or the parent theme?

Answer 1

Your site is not using a Child Theme.

It is currently using the WordFruit Theme, and this Theme does not declare any Theme as a Template. If it were, you would see a Template: parent-theme header tag (where "parent-theme" would be, e.g. twentyeleven if it were using Twenty Eleven as its parent Theme) in style.css

Thus, WordFruit appears to be a stand-alone Theme.

So, if you want to make changes to WordFruit, you would need to make changes to the Theme directly, or create a Child Theme that uses Wordfruit as its template (Parent Theme).
