Why dont you just create a column in your database which is a string data type, store the file name in that column, then you can reference the file from a central store.
For instance, say you have a images folder under your root directory.
your table could look something like this.
ID - Image Name
1 test1.jpg
2 test2.jpg
you could just pull the information out of the database and build the full path and display the images, or build them into a hyperlink, whatever you want to do. I have never been 100% keen on saving files inside the database, but i am sure people would disagree with me.
e.g. String strFile = "/images/" + yourFilePath;
sorry for the very brief example, hope this gives you a start.
