If there is really no additional description in the database, I guess you ronly solution would be to check for specific headers. All file formats have them. Perhaps you kind find a piece of code that does this for you.

Dear Pritaeas
Thank you for your reply
it seems that your solution is Correct but I don't know how can I do that
how can read header of picture data that is stored to database ? and how can find the format of picture from that?
thank you

You can google for formats and code. One of them is this one, the only one I used:
