FTS giving me no results

hi

FTS gives me no results all the time.

from the beginnning i have created table with columns: ImageColumn
(Image), document_type(varchar(4)) and filepath(varchar(200))
i have created FullTextIndex on column ImageColumn and type -
document_type.

no i have an application which convert documents to binary and i
insert them to ImageColumn column. As i open the table i see <binary
data> on ImageCol column. It is correctly presented cause i have read
data from that column and usedBinaryWriter and as a result i had the
same document file.
in document_type column i have extensions = doc or htm

i use queri in SQL console
Select * from cm_search_documents WHERE FREETEXT(ImageCol, 'a')
and it gives me no results every time...

I have SQL Server 2005 and enabled FTS cause it works on strings...

anyone?
thanks in advance
