Image.FromFile and Deleting the Image

[bbman]

Hey,
I want to create an image from a file, and then have the file deleted (or moved) after. How could I achieve this? I tried using using(), streams, Bitmaps etc. I'm completely stumped. Any help would be great.
Thanks

Edit, the problem is that I cannot delete/move the file, as it is in use (by the image I presume).

System.IO.File.Delete(FilePath);

System.IO.File.Delete(FilePath);

No, the problem is that I cannot delete it because the image is using it.

Here is the code:

a = string[] of files.
It's a bulk uploader. Now oddly, when the resize function (below) is called, it actually works - the file is released.

private Image ResizeImage(Image img, int width, int height, bool aspect)
{
    if (aspect)
    {
        if (((width * 100) / img.Width)
            < ((height * 100) / img.Height))
            height = (img.Height * width) / img.Width;
        else
            width = (img.Width * height) / img.Height;
    }
    img = (Image)(new Bitmap(img, width, height));
    return img;
}

Reasonable! :) should have typical copy on temp folder and work on it, if your operation successed then you delete the original one.

My bad! It was an error with something else.

Edit: Nope. I fixed it. I want something a little less resource consuming. Writing files everywhere will just slow it down.

Work with MemoryStream it may help to separate your operations and the physical file.

Thanks for your help. I did:

using (Stream st = new FileStream(a[i], FileMode.Open))
{
    img = Image.FromStream(st);
    st.Close();
}
