Subject: Tiff image in Blob fields

Someone please correct me if I wrong here. All the info I can get the better. :)

I am using Interbase. I have a field called IMAGE of type Blob, by default this is a subtype 0 seg 80.

I also am using TTiffGraphic(Envision) and TStreams to move the object around. I create the stream, and assign the object into it. The stream is associated with the field.

When I goto save it, I get Not a valid Bitmap image (or something similiar to that).

IF I leave the image as a bitmap, all works well. I can't leave it as a bitmap though because of the size, I mean, I could, but it is a waste of space and eventually would clean out the extra drive space and would also be slow. Tiff is a proper choice for me since all my images are BW (and nothing special).
I don't believe it to be a Database field problem since I really only have three choices and I feel that 'subtype 0' which stores raw binary data is the correct type. Other is user defined and subtype 1 is for text blob data.

Please help while I still have hair! :P
