I want to display post thumbnails and hyperlinks in post on my feed page. I know in templates you can copy page template and modify it, but here i am dealing with wp-includes/feed.php or wp-includes/feed-rss . I have two question
- what can i do get to get thumbnails of post and links of post?
- If i edit the feed template, tomorrow when wordpress updates, it will remove my custom code, how can i make it like a child-template, so my code doesn't get disturbed, when new updates come.
