In my .html.erb I wrote:

\<%= image\_tag @displayPath %\>

@displayPath = ‘invalid\_plot.png’ when the .erb is rendered.

Viewing the page source in FF I find:

![Invalid_plot](https://test.ruby-forum.com/images/invalid_plot.png)

The file exist in \<rails\_root\>/images, but FF fails to display the .png.  
Instead the als text is displayed.

Entering /home/devel/Aptana RadRails  
Workspace/rails\_root/images/invalid\_plot.png into FF displays the  
content of the file.

What is wrong?

What’s with the camelCase? That should be @display\_path.

Your image should be in RAILS\_ROOT/public/images . Remember that the  
public directory is the actual webroot.

Hi Fritz,

Do you have a public directory? Images should be inside the public  
images directory so browsers can have access. Is FF the only browser  
that will not render the image?

Also, can you go to [http://www.yourdomain.com/images/invalid\_plot.png](http://www.yourdomain.com/images/invalid_plot.png) ?

Chris

This is, what I did - it doesn’t work. Moving the file to  
…/public/images works.
