Hello everybody!

I have an issue with dynamics images in Casper theme. Post featured image by default are so big. When I customize post.hbs from this:

```
  <img class="post-image"
    srcset="{{img_url feature_image size="s"}} 300w,
            {{img_url feature_image size="m"}} 600w,
            {{img_url feature_image size="l"}} 1000w,
            {{img_url feature_image size="xl"}} 2000w"
    sizes="(max-width: 1000px) 400px, 700px"
    src="{{img_url feature_image size="xl"}}"
    alt="{{title}}"
/>

```

To this:

```
<img class="post-image"
            srcset="{{img_url feature_image size="s"}} 300w,
                    {{img_url feature_image size="m"}} 600w,
                    {{img_url feature_image size="l"}} 1000w,
                    {{img_url feature_image size="xl"}} 2000w"
            sizes="(max-width: 1000px) 400px, 700px"
            src="{{img_url feature_image size="m"}}"
            alt="{{title}}"
        />

```

Nothing happens. I’m thinking maybe dynamic images is not working in my ghost installation or maybe is wrong code in post.hbs?

In other hand, there is a recommended image defat sizes?? for example featured images form tags.hbs not appear full size.

Thanks in advance 😃

Could you not fix this issue with CSS Code injection for the site?
