Returns an <img> tag pointing at a random image served by the
Lorem Picsum API, ready to be dropped inside a
Shiny UI for quick prototyping. No network request is performed by this
function: only the URL is built, the image is fetched by the browser.
Usage
random_image_ext(width = 400, height = 400, seed = NULL)
Arguments
- width, height
image dimensions, in pixels. Single positive
(finite, whole) numbers.
- seed
optional seed making the picked image stable across calls. Any
atomic scalar; it is coerced to a string and URL-encoded. When NULL
(default), a fresh random image is served on every request.
Examples
random_image_ext()
#> <img src="https://picsum.photos/400/400"/>
random_image_ext(width = 400, height = 600, seed = "caramba")
#> <img src="https://picsum.photos/seed/caramba/400/600"/>
