Web Api 2 - How to return an image (MemoryStream from Azure Storage) from a HTTPGET without saving to disk?
From the client side you don't need to use $http. You can simplify the process by using plain old HTML...
<img src="/api/PhotoSubmit/GetPhoto/2232" />
For dynamic images use JQuery like this...
$('#ImageLocation').html('<img src="/api/PhotoSubmit/GetPhoto/' + intID + '" />');
The web browser will automatically do the work of making an HTTP Request for the image, saving you all the complexity.
On the server side, you can use a process like these to load the file and stream it to the client. It's important that the Server code return the correct MIME type such as...
context.Response.ContentType = "image/png";
