Rails Images not showing, code looking for images with file name ._image.jpg

In my application I show a selection of images on the home page. These images are all the same size and are named new1.jpg - new17.jpg and are stored in /public/images/rotate

I'm using some code found online to display a random selection of the images. This is what I'm using:

def random_image
  image_files = %w( .jpg .gif .png )
  files = Dir.entries(
    "#{Rails.root}/public/images/rotate" 
  ).delete_if { |x| !image_files.index(x[-4,4]) }
  files[rand(files.length)]
end

And then in my partial:

<img src="/images/rotate/<%= random_image %>"/>

This works perfectly running locally on my mac with rails server, when I push code up to my server on the web half of the images load, and the other half (number seems to change) display a broken image.

When viewing the source code, all images that work are looking at /public/images/rotate/new1.jpg etc, all the broken images are looking at /public/images/rotate/._new10.jpg etc They all have a '._' before the file name.

Can anyone please shed any light on this for me?

Many thanks

Ended up creating some code that deletes all of the hidden files beginning with ._ from the directory. Then it only outputs the correct images.

Try like this:

def random_image
  File.basename(Dir["#{Rails.root}/public/images/rotate/*.{png,gif,jpg}"].sample)
end

Since Dir takes a glob, * will match all files, but excludes dotfiles. Then you can ask for any allowed extension. See here: http://ruby-doc.org/core-2.0/Dir.html#method-c-glob
