How to split a .gif in frames?

Question

All the codes I've found give me the same result: a bunch of exact looking frames. Meaning: it gives me a list of the first frame, repeated X number of times. The .gif I'm using has 30 frames, so I get 30 times the first frame, instead of the 30 different frames.

    public static Image[] GetFramesFromAnimatedGIF(Image IMG)
    {
        List<Image> IMGs = new List<Image>();
        int Length = IMG.GetFrameCount(FrameDimension.Time);

        for (int i = 0; i < Length; i++)
        {
            IMG.SelectActiveFrame(FrameDimension.Time, i);
            IMGs.Add(IMG);
        }

        return IMGs.ToArray();
    }

What am I missing? ALL the codes I've looked give the first frame repeated X numbers of times.

This is what is supposed to look (using a webpage). See how each frame is different?

This is what it looks for me after saving every frame inside that array on a folder location (a bunch of equal frames):

P.S.: Yes, it's a .gif the image I'm using.

Update: The problem seems to be when I read the file in the OpenFileDialog, as it works if I pass my .gif by code. So how do I read an animated gif in the OpenFileDialong? Thank you.

   IMGs.Add(IMG);

That's the bug, you are adding the same IMG object over and over again. You need to make a deep copy of the frame. That's very easy to do:

   IMGs.Add(new Bitmap(IMG));
