In my template I have this line:
<% IO.inspect @images %>
which correctly prints what is expected:

This line correctly shows the first image in the images list of URLs:
<img src="<%= Enum.fetch!(@images, 0) %>">
However, this line:
<%= @images |> Enum.map fn(image) -> IO.puts "<img src='" <> image <> "' height='150px'>" end %>
Gives me an error saying that only lists of lists or binaries work.
Does anything look suspicious in my map? I want to map across the list and essentially print <img src="<%= image_url %>"> for each.
