Furthermore, you should keep the image in a variable, as images need to be disposed of when done

Graphics reduced_images = Graphics.FromImage(Image.FromFile(dialogPhoto.FileName));
...
reduced_images.Dispose();   // not present in OP

Image img=Image.FromFile(dialogPhoto.FileName);
Graphics reduced_images = Graphics.FromImage(img);
...
reduced_images.Dispose();
img.Dispose();
