不知道你是用什么方法读写的?
我用DBImage控件,从文件装入200K - 1.5G的图片,都没有什么问题呀!
DBImage1 - DataSource1 - ADOTable1 - ADOConnection1
procedure TForm1.Button6Click(Sender: TObject);
begin
if OpenDialog.Execute then
begin
if not (ADOTable1.State in [dsInsert,dsEdit]) then
ADOTable1.Edit;
DBImage1.Picture.LoadFromFile(OpenDialog.FileName);
ADOTable1.Post;
end;
end;
