Storing Images in DB - Yea or Nay?

HighLights:

• Database is for a structured data.
• Long Run performance hit and backup .
• Small static images (not more than a couple of megs) that are not frequently edited, should be stored in the database. This method has several benefits including easier portability (images are transferred with the database), easier backup/restore (images are backed up with the database) and better scalability (a file system folder with thousands of little thumbnail files sounds like a scalability nightmare to me).
