rails 4 asset pipeline vendor assets images are not being precompiled

Question

I'm using rails 4 & ruby 1.9.3 for my application and fancybox2-rails gem, but there's a general problem with asset pipeline. If I run rake task for precompile, then everything is fine except for images in vendor/assets/images and ../gems/ruby-1.9.3-p327/gems/fancybox2-rails-0.2.1/vendor/assets/images. Images from these two folders are not being precompiled and eventually I have a problem with dead links to non-existing images. Any suggestions?

Answer 1

It seems like images are included by default only from app/assets folder. So the solution is to add this line to config/application.rb

config.assets.precompile += %w(*.png *.jpg *.jpeg *.gif)
