Inject/transform image paths?

Is it possible to use gulp-inject to rewrite image paths? I am using gulp-inject to modify the paths of css files to replace the domain for local vs test environments like so:

```

//...
.pipe(inject(css, {addPrefix: cdnPrefix, addRootSlash: false}))
```

This transforms the css file to:

```

```

I am attempting to use this same method to rewrite the paths of image files using the `options.name` property, like so:

```

//...
.pipe(inject(css, {addPrefix: cdnPrefix, addRootSlash: false}, {name: 'images'}))
```

However the image tags in this region are not being transformed. In reading through the documentation, I have only seen examples using JavaScript and CSS files... Is this part of gulp-inject, or should it be able to handle any filetype? If so, is there documentation around injecting/transforming file paths like I am attempting?

Start with the gulp-inject documentation examples for JavaScript and CSS, then examine how the `name: 'images'` region and `addPrefix` option are handled. Reproduce the reported HTML example and determine whether image-path rewriting is supported; done means documenting the supported behavior or a clear limitation.
