Displaying IMAGES from a DATABASE into a MARQUEE

This is a simple project. It shouldn't be too hard or take too long. I need someone to write a script for me that would display random images from a database. Bottom line: Website is built using PHP and has SQL datase access. Website is for a used car dealership. Cars are added and removed daily. I need a script that goes into the database and grab a random image from any vehicle that is currently in the database. And I need this random image to be put into a marquee, along with more random images until all of the images in the database are used. There would be about 20-40 images in total. Then the marquee would loop. You will include codeing for the size of the marquee and size of the images. It should be made so I can change the size myself if I have to. If you think you could do this let me know. Can it be done using php? How do you plan to do it?
