Hmmm.... I can't seem to pass blobs to an update or insert query.
Any ideas?

sQ :=
'INSERT into SIGNATURES ' +
'(SINVLOOKUP, BARCODE) Values '+
'('+ QuotedStr(sInvLookup) + ', :Barcode)';
Active := False;
SQL.Clear;
SQL.Add(sQ);
TBlobField(ParamByName('BARCODE')).LoadFromFile(sJPEGFile);
Active := True;

Thanks in advance
