If you didn't want to store and retrieve the images through MySQL, you can store
the path information instead. That way you only have to use and maintain a
simple string of text.
Since you want to display images in your HTML, they would usually be stored in
your web space. You can use SQL to build some type of query (e.g. sort by date,
name, etc) and dynamically print the results in your HTML using the file name
and/or path information.
