+## Usage
+
+Create the filter:
+
+```go-html-template
+{{ $filter := images.AutoOrient }}
+```
+
+{{% include "functions/images/_common/apply-image-filter.md" %}}
+
+{{% note %}}
+When using with other filters, specify `images.AutoOrient` first.
+{{% /note %}}
+
+```go-html-template
+{{ $filters := slice
+  images.AutoOrient
+  (images.Process "resize 200x")
+}}
+{{ with resources.Get "images/original.jpg" }}
+  {{ with images.Filter $filters . }}
+    <img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
+  {{ end }}
+{{ end }}
+```
+
+## Example
+
+{{< img
+  src="images/examples/landscape-exif-orientation-5.jpg"
+  alt="Zion National Park"

+
+The `math.Rand` function returns a pseudo-random number in the [half-open interval] [0.0, 1.0).
+
+```go-html-template
+{{ math.Rand }} → 0.6312770459590062
+```
+
+To generate a random integer in the [closed interval] [0, 5]:
+
+```go-html-template
+{{ math.Rand | mul 6 | math.Floor }}
+```
+
+To generate a random integer in the closed interval [1, 6]:
+
+```go-html-template
+{{ math.Rand | mul 6 | math.Ceil }}
+```
+
+To generate a random float, with one digit after the decimal point, in the closed interval [0, 4.9]:
+
+```go-html-template
+{{ div (math.Rand | mul 50 | math.Floor) 10 }}
+```
+
+To generate a random float, with one digit after the decimal point, in the closed interval [0.1, 5.0]:
