I want to add images in a panel. Each image size is 5 to 6 MB. If I add more than 35 images then it shows error that "Out of Memory". This exceptions occur when Image.FromFile(string) is executed. If less than 35 images is loaded then no error shows.

C#

if (DialogResult.OK == ofdLoadFromHDD.ShowDialog())
                {

                    string[] strArray = ofdLoadFromHDD.FileNames;
                    int count = strArray.Count();
                    DynamicGroupBox objDGB = new DynamicGroupBox(scrolledValue);
                    GroupBox gB = new GroupBox();

                    try
                    {
                        for (int i = 0; i < count; i++)
                        {
                            Bitmap bmp = (Bitmap)Image.FromFile(strArray[i]);

                            CommonInformation.SCANNING_NUMBER++;
                            objCommonUtility.replaceImageIntoDB(bmp, CommonInformation.SCANNING_NUMBER.ToString());

                            gB = objDGB.createGroupBox(bmp, CommonInformation.SCANNING_NUMBER, false);

                            pnlImageContainer.Controls.Add(gB);

                        }
                        gB.Select();
                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message);
                        CommonInformation.SCANNING_NUMBER--;
                    }
                }

What do you expect for a solution: showing of 100s of such file at the same time or what?

Yes, I need to load images greater than 500.

May be your RAM memory is low? How much is that?

Memory is 2 GB

This is not a problem per se. You just need to remember: there is no such thing as miracle. No matter what you do, eventually you can deplete your memory if you allocate too much at the same time. Well, you can have more memory with 64-bit system, but this is not a solution as the memory is always limited.

Instead of raising this pointless concern, think about this: who needs to 35 6M images at the same time? Load them on request; loading of a file of this size is very quick. After all, present many images in the form of small thumbnail, possibly obtaining those thumbnail on the fly by re-sampling each image to a small size, which is also a fast operation. On demand, show full-size image, one two at a time. Who needs more? If you make it convenient, you won't hear from your users anything except thank you.
