That would depend on what version of WordPress you are running, which theme you have chosen, and any plugins in use that may include or modify such functionality.
A site link also may help along with a note as to which posts you are having this issue with?
In my self seo blog – sergey-oganesyan.ru i will be to do the same thing, if possible, then immediately tell!
My wordpress version 3.2.1
I don’t have any plugins that do this, just the built in wp widgets like recent post.
In any case, what plugins do you recommend to resolve my problem?
To have featured images in a list of you recent posts in a widget, rather than modifying the functionality of the core featured posts widget, you could use a plugin to add a widget that has the required functionality – such as http://wordpress.org/extend/plugins/yd-recent-posts-widget/
I am not that good in adding codes. Do you have any example how the widget will appear in the right side bar?
You don’t need to add codes, just install the plugin and add a widget to the sidebar. Or look at the plugin description and view the screenshot.
