Photo Uploader & background Changer

This project is a small one. I need someone that has ClipShare Video Script experience. I need a background changer. Where the admin can log into the backend. Upload background image via form and it will replace the background image in the .css (whereever the background is locate in the script. The easiest way for it to work - [login to view URL] has ../images/[login to view URL] - this needs to have path to /v/images/ So when image is uploaded image [login to view URL] is called to the [login to view URL] So, the last uploaded image will show in the background of the site. I want it so that the older uploads remove automatically when an new image is uploaded also a mini thumbnail will show where the form is available. The form for upload background tool can be a created tab or placed anywhere in the admin panel.
