### My tweaks
As I mentioned earlier, I want to have basically three recipes for baking my OG images: one for the homepage, one for standard posts, and one for posts with an associated thumbnail. They'll all use the same basic code, though, so I wanted to be sure that my setup didn't repeat itself too much.
I'll start with fetching my resources up front, and initializing a `$text` variable:
```jinja-html
// torchlight! {"lineNumbers": true}
{{ $img := resources.Get "og_base.png" }}
{{ $font := resources.Get "/FiraMono-Regular.ttf" }}
{{ $text := "" }}
<meta property="og:title" content="{{ .Title }}" />
<meta property="og:description" content="{{ with .Description }}{{ . }}{{ else }}{{if .IsPage}}{{ .Summary }}{{ else }}{{ with .Site.Params.description }}{{ . }}{{ end }}{{ end }}{{ end }}" />
<meta property="og:type" content="{{ if .IsPage }}article{{ else }}website{{ end }}" />
<meta property="og:url" content="{{ .Permalink }}" />
<meta property="og:locale" content="{{ .Lang }}" />
```
If it's the homepage, I'll set `$text` to hold the site description:
```jinja-html
{{- if .IsHome }}
{{ $text = .Site.Params.Description }}
{{- end }}
```
{{- if .IsPage }}
{{- $iso8601 := "2006-01-02T15:04:05-07:00" -}}
<meta property="article:section" content="{{ .Section }}" />
{{ with .PublishDate }}<meta property="article:published_time" {{ .Format $iso8601 | printf "content=%q" | safeHTMLAttr }} />{{ end }}
{{ with .Lastmod }}<meta property="article:modified_time" {{ .Format $iso8601 | printf "content=%q" | safeHTMLAttr }} />{{ end }}
{{ $text = .Page.Title }}
{{ end }}
