ruby on rails link_to an image -

-

i'm facing following problem: have small image gallery image files located in following directories

 app/assets/images/locale/thumbs/  app/assets/images/locale/big/

i have create hyperlink content has thumb image , target - bigger version app/assets/images/locale/big/ folder: 

<a href="path-to-full-size-image-001.jpg">  <img alt="first photo preview" src="/assets/locale/thumbs/001.jpg" /> </a>

i'm doing means of

= link_to(image_tag("locale/thumbs/001.jpg"),  "locale/big/spizzicaluna001.jpg")

in fact have tried many variants second argument of link_to little success - bigger file can not found.

how resolve issue?

there 2 approches issue.

  1. you must specify assets folder in path.

    link_to( image_tag("locale/thumbs/001.jpg"), "/assets/locale/big/spizzicaluna001.jpg" )

  2. use image path allowing rails find correct image

    link_to( image_tag("locale/thumbs/001.jpg"), image_path( "locale/big/spizzicaluna001.jpg") )
