Upload image to imgur from another URL

Hi folks,

I am writing app in C# which should provide to user imgur link of picture which already exists on some other URL (so, not from local machine). I have implemented app so far (dummy) that app downloads image from its original URL and then local copy of image is being uploaded to imgur server and I get my imgur URL. I set image property in this way:

{ "image", Convert.ToBase64String(File.ReadAllBytes(localFileName)) }

So, basically, I read image locally from machine and pass that byte stream converted to base string in my request.

My question is: Is there a way not to do that, but to send URL where image is located and that I become imgur URL of that image without saving it locally on machine before making request to imgur server?

Many thanks in advance for any kind of answer.

Best regards.
