I am thinking of setting up my own shopping cart and was wondering if it is possible to put pics into a database to make it easier to change the pics and just call up the data base to output to the website?
You can do it if you define a column's type to be "BLOB" (Binary Large OBject). I think storing all the picture details in a column is not much better than storing a URL of an image.
You could store just the picture names in your database. I don't see a problem in that!
