hi, U can use instance of Bitmap class like this Bitmap b = new Bitmap(...) ans use public Save method to save image with format ImageFormat.Gif and if u want to resize image , try this code , hope it help

public Size CalculateDimensions(Size oldSize, int targetSize)
{
Size newSize = new Size();
if (oldSize.Height > oldSize.Width)
{
newSize.Width = (int)(oldSize.Width * ((float)targetSize / (float)oldSize.Height));
newSize.Height = targetSize;
}
else
{
newSize.Width = targetSize;
newSize.Height = (int)(oldSize.Height * ((float)targetSize / (float)oldSize.Width));
}
return newSize;
}

the oldSize param is old size of your image the targetSize param is new dimension you want to resize to.
