Subject: Re: scruffy question

I'm not familiar with what you are doing, but I'm pretty sure you need  
to save the file in a public directory. Save that path as a variable  
which you can use in the view.

And on a side note, url_for(:action) just builds the relative path for  
the page show_img creates. url_for is for building relative links to  
other controllers and actions. These paths are not real paths in your  
public directory, they are virtual paths rails builds for you when you  
request them.

The rails list would be your best bet for more in depth help.
