Hi. I just did a job like this for another person (check my feedback). I can modify your existing CMS to allow you to add extra product images, I can display those images on your public site, and I can fix whatever bug you have (as long as it doesn't lead down a rabbit hole). I have years of experience in PHP, (My)SQL, and Web programming. Please check my PM. Oh, and I can start immediately, and finish before the end of the day.
