I have some image files under

/app /uploads   /images/     111.jpg

/public   /images

.

How can I user image_tag to display the images under /uploads/images/...?

Any hints?

Hi Jochen, you can create symlink in public dir that would point to uploads.

But the files must be protected...when I create a syslink everyone is able to access them! Right?

protected from what? In what cases do you want users to be able to view these images?

Only logged in users are able to view the files.

When I store the images under /public/images/111.jpg everyone is able to view the images.

But I thing I got a soultion:

send_file RAILS_ROOT + "/downloads/#{params[:galery_id]}/#{params[:filename]}", :type => "image/jpeg", :disposition => 'inline'

beware that send_file keep files in memory until they are downloaded, so that means you could get in trouble with big files or many downloads at time.

You can also use the X-Sendfile header to send non-publicly accessible files through the web server (providing that it supports this header), without tying up your rails process. You can read more about it here:

or create own x-send_file method that would create symlink with unique name and redirect logged user to it. Clear can be done with cronjob.
