ImageList.Image s.Add problem

Hi,

When I add an image dynamically at runtime to an ImageList, the image is
added but with the problem that all the images are added with black pixels
surrounding them.

Example code:

for(int i = 0; i < openFileDialog1 .FileNames.Leng th; i++)
{
Image image = Image.FromFile( openFileDialog1 .FileNames[i]);
imageList1.Imag es.Add(image);
}

Is there a solution for that ?
Regards
Luis A.
