# Then all images are available as such: window.assets['my_image.jpg'] |
Oh great! Exactly what I needed.
I probably wasn't clear with my question then :)
For use within the asset pipeline, we have to import ApplicationHelper:
# assets.coffee.erb
<% environment.context_class.instance_eval { include ApplicationHelper } %>
window.assets = <%= asset_paths_to_json(:images) %>
I think this will work:
window.assets = <%= ApplicationHelper.asset_paths_to_json(:images) %>
Doesn't work for me.
You are right. My mistake.

I created a little helper for the matter. It does not only look for assets in 1 path but in any path where assets are stored (/lib/assets, /vendor/assets, ...) - even in gems.
Then you can do:
