Why im getting in the pictureBox1 white background with big X red instead the animated gif ?

[EDN Admin]

I checked on the hard disk the animated gif is created and i opened it in internet explorer and it worked.
So i dont understand why im getting this white with big x red.
I used breakpoint and didnt get any errors so far.

This is the class im doing the animated gif:

[/code]
The real creation of the animated gif in this class is this line number 175:

<pre class="prettyprint unfreez.MakeGIF(myGifList, previewFileName, 8, true);[/code]
And the animated gif is realy exist and created.In line 210 im calling the function that load the animated gif to the pictureBox:

<pre class="prettyprint pictureBoxImage(previewFileName);[/code]
And this is the pictureBoxImage function where i used breakpoint and it didnt show any errors:

<pre class="prettyprint public void pictureBoxImage(string pbImage)
{
Image img2 = null;
try
{
using (img = Image.FromFile(pbImage))
{
//get the old image thats loaded from the _memSt memorystream
//and dispose it
Image i = this.pictureBox1.Image;
this.pictureBox1.Image = null;

if (i != null)
i.Dispose();

//grab the old stream
MemoryStream m = _memSt;

//save the new image to this stream
_memSt = new MemoryStream();
img.Save(_memSt, System.Drawing.Imaging.ImageFormat.Gif);

if (m != null)
m.Dispose();

//create our image to display
img2 = Image.FromStream(_memSt);
}

if (img2 != null)
pictureBox1.Image = img2;
//label2.Text = numberOfFiles.ToString();
//label6.Text = nameOfStartFile.ToString();
//label4.Text = nameOfEndFile.ToString();
//File.Delete(pbImage);
}
catch (Exception err)
{
Logger.Write("Animation Error >>> " + err);
}
}[/code]

Cant figure out why ? The red x and white background.
