Adding Thumbnails with database

I went through the [SIZE=4][COLOR=#003366][SIZE=2][COLOR=#000000]Adding Thumbnails tutorial.[/COLOR][/SIZE][/COLOR][/SIZE]
[SIZE=4][COLOR=#003366][SIZE=2][COLOR=#000000]Works great. Is it possible to retrieve the text and image location information from a database and load that into the xml page?[/COLOR][/SIZE][/COLOR][/SIZE]
I can create an application using asp to upload this information into say, an access database.
Would like to somehow upload the images and modify the text thru a backend application.
Fairly new at this, please forgive if I am way off track.
