Create a RSS-based embeddable widget

I need a "widget" created that will allow other sites to automatically embed our daily content from [login to view URL] The site is a custom CMS and the data is in a MySQL database. The content updates daily at 12pm PST and the widget will need to update as well. The idea is to give other websites a snippet of code they can paste on their external site and it will show today's content from our site, show our logo, and link to our site. Size will probably be about 250px x 250px, but I'd like a few options. The widget will include: - Site logo - Name of content writer (changes daily) - First couple lines of content - Link back to site It would be the same info as the RSS, viewable here: [login to view URL] Please include what type of widget you would create. A php-generated image? A javascript embed? Something else? The final product will need to run on our server and be written in PHP. Thanks!
