Access asset from asset-pipeline inside a gem

Hi @ all,

I have a gem, which implements an engine, to provide assets. Pretty much
like the following example:
How to Build a Rails Engine | Brandon Hilkert However, my
gem serves images.

In a rails app, I can access the image using image_path - so far so
My problem now is, how can I access these images from another gem?

This other gem is part of my rail app. But when I access the image from
there with image_path, I get images/foo.png rather than asses/foo.png.

It seems the asset-pipeline cannot find the image when calling this from
the gem.
Does anyone know, how do I access assets from a gem?

Thank you in advance!
