WordPress MU

I have successfully uploaded and activated "Flexible Upload" Plugin to my blog via "Plugin Central". I want to add an image to my sidebar. When I go into Design>Widgets I do not see this widget as an option. How do you use this plugin to add an image to a blog?

Link to plugin homepage would help.

oh god, I saw this post and thought we could safely ignore it.

here is the link: http://blog.japonophile.com/flexible-upload/

the description from the plugins page:

Flexible Upload is a plugin for Wordpress 2.0.x, 2.1.x, 2.2.x, 2.3.x and 2.5 to enhance the image upload functionality.

Main Features

* Resize pictures at upload to the size you specify
* Let you decide whether or not to create a thumbnail and specify its size
* Optionally incrust a watermark signature in all pictures you upload
* Specify picture alignment (left, right, center) when inserting them into your posts
* Specify a plugin like Lightbox (Thickbox, Greybox) to display your pictures, or open them in a separate window
* Insert a caption for each picture
* Multi-language support

WHERE DOES IT SAY ANYTHING ABOUT A WIDGET?

besides, this might be spam? http://mywebbizexposed.com/blog/ looks ok, but check http://mywebbizexposed.com/
anyway even if its a legitimate question, its a really annoying one as this person doesn't even seem to be runnning wpmu but WordPress 2.6.2

To put an image in your sidebar, you type in the HTML img tag in a text widget. :)
