ImageResizer does not redirect local image url to azure cdn url?

I have the following configured in my web.config:

<resizer>
    <clientcache minutes="1440" />
    <plugins>

    </plugins>

  <plugins>
    <add name="AzureReader2"
         connectionString="DefaultEndpointsProtocol=https;AccountName=myaccountname;AccountKey=myaccountkey="
         endpoint="https://az824306.vo.msecnd.net/"
         prefix="~/" />
  </plugins>
    </resizer>

I have a directory called bdgtpd under the root of my website and in there I have one image 40420_1.png.

I also have this image on azure located at:

https://az824306.vo.msecnd.net/bdgtpd/40420_1.png

Initially, I had my src set to https://az824306.vo.msecnd.net/bdgtpd/40420_1.png, but when I tried to apply something like https://az824306.vo.msecnd.net/bdgtpd/40420_1.png?width=300, it did not work.

So then I set it to:

<img src="~/bdgtpd/40420_1.png?width=300 />

and this does resize the image, but when I look in the chrome console, I can see it is grabbing the image from my local folder. Maybe I don't understand the AzureReader2 plugin, but I thought it when it sees:

http://localhost/bdgtpd/40420_1.png?width=300, this would be fetch the image from https://az824306.vo.msecnd.net/bdgtpd/40420_1.png and apply the transformation.

Am I setting my src right? Should it be a local url or the cdn url?

Ok, so I deployed ImageResizer along with AzureReader2 to my staging server and I am pointing my images to my staging server. When I set the prefix to ~/, the site threw 404 error and there were messages such as Blob Not Found. All the images on the home page are in the CDN. When I make the prefix ~/azure/, it works fine, so I am not sure what is going on here.

I was looking at the could architecture documentation, but I am confused on a couple things:

  1. Right now I have one image that has the ~/azure/ prefix path set, so when I look in the chrome console under the network tab, I see the initiator is my staging server path, but the image is actually being pull from the cdn. It would be great to have a simple explanation of what is happening.
  2. When I use clientcache, if a user requests the same image from the cdn, how is the image delivered? I wasn't sure exactly how this works?

Thanks so much

If ImageResizer is running on localhost (for example), then your URLs should point to localhost. Azure doesn't have any magic ability to understand ImageResizer commands and execute them; you have to talk to the server with ImageResizer installed.

You should configure AzureReader2 with a prefix (like /azure/), although it appears you've discovered that this works?
