We (or I should say they, since I am ETRG) use oracle intermedia to store images on the database as blobs in tables and modify these images (since they often need resizing and cropping).
For displaying the images(blobs) we use a web interface.
Using intermedia you can import and export images, once exported into windows you can view them with any photo viewer.
