I'm assuming that you've already got product descriptions that you can parse and pull out keywords. This is a brand new project with brand new products (actually clipart and photos). I don't even have a starting place for generating a keyword list. I'm gonna have to have some type of form for uploading images and choosing the associated keywords. And, then of course, if the keywords are in a separate table, although easy to do, I've still got to create a form for adding possible keywords. I'll let you know if someone responds with a better structure.
