Web Development

I am looking to set up a website that has a discussion forum - open to the public to read but registration required to post. I would like to have the images that are posted stored in a database. After 30 days would like the images on the forum to be archived in this database. The database would be searchable - and would require registration to search.

I have done some research and found some products that seemed to be focused on this area - such as:

http://www.minihttpserver.net/bbs/index.php
http://www.sharing-file.com/index.htm

They are inexpensive and seem to do what I need.

Does anyone have advice - or experience with these products? Is this the right approach?

Thanks
Jim
