This is a guess of sorts but I think if you load TGifImage into your project
this error might go away for the Graphic field.
I generally use a FileStream to stream the file into the field like this:
procedure LoadImage(fld: TBlobField; const sFile: String);
var
fs: TFileStream;
begin
fs := TFileStream.Create(sFile, fmOpenRead);
try
fs.Position := 0;
fld.LoadFromStream(fs);
finally
fs.free;
end;
end;
