When you use Image.FromFile to read an image from a file, the file is locked. The following method reads an image from a file without locking it:

public static class Utils
{
    public static Image ImageFromFile(string fileName)
    {
        if (fileName == null) throw new ArgumentNullException("fileName");

        using(FileStream lStream = new FileStream(fileName, FileMode.Open, FileAccess.Read))
            return Image.FromStream(lStream);
    }
}

Here's an example how to use it:

// old method that locks the file:
Image img = Image.FromFile("picture.jpg");
// new method that does not lock the file:
Image img = Utils.ImageFromFile("picture.jpg");
