Windows窗体中的Web浏览器控件未显示图像

Question

I am developing an application that registers a student and then prints out an identity card.

On my main form, I have an image Picture box control in which the user loads the image of the student.This image box stores the image in the hard drive through the following code:

string result;

        DialogResult res = ofdDialog1.ShowDialog();
        if (res == DialogResult.OK)
        {
            result = ofdDialog1.FileName;
            pbImage.ImageLocation = result;
            pbImage.SizeMode = PictureBoxSizeMode.StretchImage;
            pbImage.Load();
            System.Drawing.Bitmap img = new System.Drawing.Bitmap(pbImage.Image, pbImage.Height, pbImage.Width);
            img.Save(Path.GetFullPath("Images/1.jpg"));
        }

To print the i-card, I am using an web browser control to first preview it to the user. I have an html code in which I want to show the details of the student with their pictures, and some logos. Everything else is working fine, but the student image is not getting displayed in the web browser control. I am using the following code:

contents = contents.Replace("[StudentImage]",Path.GetFullPath("Images/1.jpg"));

contents variable contains the HTML,

Following is the part of the html that should show the image of student:

<div style=""float:right; width:100px;height:95px;"">
<img src=""[StudentImage]"" style=""width:85px;height:85px;"" />
</div>

What am i doing wrong when all other images are showing perfectly with this approach except for this?

Answer 1

You can use this method to submit your HTML content to the webbrowser

 private void DisplayHtml(string html)
 {
     webBrowser1.Navigate("about:blank");
     if (webBrowser1.Document != null)
     {
        webBrowser1.Document.Write(string.Empty);
     }
      webBrowser1.DocumentText = html;
  }

The use line

DisplayHtml(contents);

Answer 2

You might need to use an absolute path for the image. I'm not sure what the WebBrowser's "current directory" would be.

Answer 3

i found the solution, instead of

img.Save(Path.GetFullPath("Images/1.jpg"));`

i used

img.Save(Path.GetFullPath("Images/1.jpg"), System.Drawing.Imaging.ImageFormat.Jpeg);

The image is now displaying correctly.
