+This is a simple aspnet middlewear that converts your small images to base64 encoded data tags in html.
+
+I wouldn't actually recommend doing this, I mostly did this to see what is possible in aspnet core middlwear. There is much [evidence](http://davidbcalhoun.com/2011/when-to-base64-encode-images-and-when-not-to/) to suggest that it is a bad idea
+
+How to use:
+
+```csharp
+public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
+        {
+
+            app.UseEmbedImages(env);
+
+        }
+
+```
+
+## Before
+
+`<img src="/path/to/img.jpg" />`
+
+## After
+
+`<img src="data:img/jpeg;base64,=randomdatahere" />`
