show an image stored in a database

Hi friends

I have an interbase 6 database. One table has a blob field holding a picture and I need to show it.
The problem is that I don't know in wish format is stored this picture. I ran a routine to show a jpg picture and it failed, I got an JPEG ERROR #52.
How can I know the format of this picture and show it?

thanks in advance

OK, I tried all this things and no results.
I saved the file to the HD and it doesn' t look like a jpg. I read the link posted by mnasman and it's very interesting but it didn't help me.
How I need this very much I'll increase my points on this question.

Thanks all
