How to display images from external RSS feeds in WordPress?

Is there any way to show an image from RSS feeds in my WordPress 开发者_运维问答page? Currently the default WordPress RSS feeds will only show the text of feeds from other sites. How can I make my site show a thumbnail image of RSS feeds of the other sites?

I'm using WordPress 3.01.
