So I'm really new to Wordpress and I'm trying to create a simple widget. I want the widget to list the logos of my site's affiliates (similar to the "check out our shows" section on http://www.howstuffworks.com/).
I also want it to be easy for the administrators to add/remove images from the list of partners. In other words, I don't want to have to modify the widget's code in order to change the partners.
At a very high level what are the steps that I might follow to build this widget?
