Using gifs in a database (Newbie)

I'm need a database table with 2 fields,
the first field is some ID-field, the second a bitmap.

Is it possible to use gifs instead of bmp's?
That saves a lot of diskspace, because the pictures
i'm talking about are scanned.

I'm quitte sure it isn't possible with standard Delphi (2.0),
But are there some components who can?

Another solution will be a piece of (delphi) Pascal code which does
the GIF->BMP conversion. So I can load a GIF-file for every record,
convert it and display it. High speed is not neccessary, but like it
allways is: the faster the better...

Please give me a hint,
