The Just a Quote Widget allows you to easily configure a quote to appear in your blog’s sidebar. Simply enter the title, quote, and source into the included input fields, and you’re done. For ease of use, there is quote-like formatting already built into the widget; if you do, however, wish to style it yourself (via your theme’s stylesheet), you’re more than welcome. Simply select the “Style the quote yourself?” option, and the default formatting will be deactivated, allowing you to go CSS-crazy in your theme’s stylesheet.
For those CSS bandits styling the widget themselves, use the .just-a-quote (for the quote text) and .just-a-quote-source (for the source text) classes in your theme’s stylesheet.

Easily display any quote from any source in your sidebar with some basic 'quote-like' formatting (and the option to style it yourself).

Use the intuitive and powerful rich text interface to add and edit quotes, 
using the ‘featured image’ functionality to add a thumbnail image. Then, use 
either the supplied widget, a simple shortcode, or a straightforward function 
in your theme to add either a specific quote or a random quote to your site.
This plugin is a fork of Perfect Quotes. I forked it because it’s an excellent 
plugin. In some ways, it’s more powerful and flexible than this one. I highly 
recommend it if this plugin is too simple for you and you don’t need either 
the thumbnail feature or the rich text editing option.
