You can easily create widget areas with the sidebar manager and display them in two clicks with the widget area shortcode generator. With the Instagram and dribbble widget, you can choose to display your images as a list of thumbnails or as a slideshow.
The “Recent post with thumbnails” widget is very complete. You can choose to display any post types, (blog post, portfolio, video or gallery). If you choose the blog posts, you can choose to display the most recent or the most commented posts and you can even choose which category to display.
