Jan asked, "Do you have a specific question?" and "Is there a reason not to use a database as a database?" and "If you need help, edit your question and insert as much details as necessary to provide any meaningful answer. If a questions looks like the asking person has spent as much work as possible to solve the problem, the contributors here will be more enthusiastic to support you."
Is the key point for you the storing of the images, or is it the retrieval of the images? Is the most frequently retrieved information the images or is it feature vectors that describe the images? What size of images are involved (in bytes)? Are there multiple images per person to be stored? What (if any) performance criteria are there? Do you have a specific reason to prefer one database over another? What binary format should the images be stored in, a plain array of bytes or (say) JPEG format?

@suny: after all it is not about the word "urgent" it is about YOU not getting any help because of YOU and YOU only.
I saw people people getting the first answer in a minute because the contributors were able to do so.
It is in YOUR interest to give the best description of your problem. If you do not get an answer and you are requested to provide more details then it could be that the description you gave is not as specific as you thought (as you could have already guessed from Walter's previous comment).
I suggest to reconsider the title of your post and to look at mySQL, a freeware DBMS, to store your images. There are plenty of ways to establish a connection with MATLAB (a hint: google).
Any problems you may encounter, post here (as indicated in my TUTORIAL: how to ask a question...)

Go to www.images.google.com type in "face", then click search and save the pictures in a directory on your computer.
If it was my homework assignment I might search with "pretty face" instead.

Why don't you save your array which contains your image data by "save" function, Matlab will put image data in a ".mat" file. and you can use "load" function to access it later as an image database.
