You need to supply the image filename as the first parameter to image_tag.

image_tag <filename>, size: <size>

For more info, please see:

I do not believe that size takes in arguments in words (i.e. large, medium, etc).

You can modify your fooimage method a bit:

def fooimage(image_path, size)
  if size == "large"
    actual_size = "200x200"
  elsif size == "medium"
    acutual_size = "100x100"
  else
    actual_size = "50x50"
  end
  image_tag image_path, size: "#{actual_size}"
end

And, call it like...

<%= fooimage "logo.png", "large" %>
