You need to provide more details e.g.:

• .net framework version
• image type
• your code sample
• any other useful data...

using (var img = Image.FromFile(srcImagePath))
                        {
                            FileInfo exportedFileInfo = new FileInfo(srcImagePath);
                            tempoImagePath = Path.Combine(_hostingEnvironment.WebRootPath , cacheDirectory) + "//" + watermark.Id + StaticVariables.CharacterSeparator + "wm" + exportedExtension;
                            if (watermark.WatermarkType.HasFlag(WatermarkType.Text))
                            {
                                img.AddTextWatermark(watermark.TextWaterMark);
                            }
                            if (watermark.WatermarkType.HasFlag(WatermarkType.Image))
                            {
                                var watermarkImage = Path.Combine(_hostingEnvironment.WebRootPath , originalDirectory , watermarkDirectory) + "//" + watermark.Id + exportedExtension;
                                img.AddImageWatermark(watermarkImage);
                            }

                            img.SaveAs(temporaryImagePath);
                            img.Dispose();
                        }

Are you sure that watermarkImage is referring to an image file correctly? I just tried with similar code and it worked fine.

btw, you may use the conditional extension methods to simplify the code as below:

using (var img = Image.FromFile("wwwroot/images/image.png"))
{
    // replace 'true' with the relevant condition check
    img.AddTextWatermarkIf(true, "TEXT WATERMARK") 
        .AddImageWatermarkIf(true, "wwwroot/images/logo.png", new ImageWatermarkOptions { Opacity = 30 }) 
        .SaveAs("wwwroot/images/new.png");
    img.Dispose();
}
