I once did something similar, but all from the interface builder using databinding, when I did it that way it automatically detected the images and displayed them.
A few small questions: does it show the column with the correct name for the images, what datatype do your images have in the database, does it work when you do it completely from the interface builder.
If it does show the column, and it has the correct name, maybe you simply need to a row height for the image to show.
Please post a reply if you need further help.
PS. As a small extra tip, take a look at app.config files. Those are ideal for storing settings like database connection strings:
