1 What are object-oriented databases and how do they differ from relational databases?
First of all, they may or may not differ. An object oriented database is a database you program by the use of small pieces, that, put together form an object. These objects can then be combined with other objects and/or be used separately. Actually, if you where to remove 'on leg' of the database that leg should be able to stand on its own. So goes the therory anyway. One relational database that has some benefits as an object oriented database is 4D. However, the stuff that one 'leg' can entirly support itself isn't actually true, however the objects are there and they do make a lot of sense. Am I making sense? --

How can you store pictures on SQL Database?
In short, the SQL database column has to be defined as either an image column or a binary column (SQL2k) In earlier versions, 6.5 & 7, they should have been defined as a BLOB (Binary Large Object). A more precise answer can be given if you supply additional information such as DB version, programming langauge used. ** As explained here you can store images within SQL server however I would not recommend this. In doing so you will bloat the database dramatically, and the reconstitution of the images when recalled from the database is a big performance hit. I would recommend storing the images within the file system (saved to your hard drive as normal) and linking the images to a database record by defining a column that hold the path and file name to the image. In doing so your database overhead is simply that field and not the entire image.
