create DATA URI's for image tags

I have a need to create data URI's for my images so that I can set the SRC attribute as the data URI in an IMAGE tag. I found the following function online, but am getting the error "URI formats are not supported.". Any suggestions on how to fix this?

imgFile is in the format of:

http://www.abc.com/someFileName.jpg

here's my code:

        public static string GetDataURI(string imgFile)
        {
            return "<img src=\"data:image/"
                     + Path.GetExtension(imgFile).Replace(".", "")
                     + ";base64,"
                     + Convert.ToBase64String(File.ReadAllBytes(imgFile)) + "\" />";
        }

Hi,

Where do you get this error? on the page? compile time? or somewhere else?

i get it when I run my console program in Visual Studio.

The code is fine. Please post your console app's code.

The console's code is literally one line, calling this function (I made a test console program to test this individual function). When I step through my code in VS, and I hit F10 right up to the return line, that's when I get the error.

it works if you give it a physical path, yes. I was trying to give it a web url. Fortunately, I was able to find a way to get the physical path to it, so I have everything I need right now.
