mySql database

I need major help Please:

I am building a photo gallery shopping cart with php. I want to use a database (MySQL) to store the information. There is, approximately 6,000 images. The cells will have an id, picture_id, description, and a price. I understand the CREAT TABLE statements, but I have no idea how to get 6000 images, descriptions etc into the database, using MySQL. I am very new to the whole database environment, so if you could please explain, using simple terminology I would highly appreciate it.
