IMG's disappear

[eluser]jedre[/eluser]
Hello,

Firstly, I dont use .htaccess file to remove index.php from URL.
I have problem with my img's.

My CI directory

Code:

index.php
/admin
/css
/js
/gfx
/img
/system
    /cache
    /codeigniter
    /[...]
    /sp <- i change application names
       /config
       /controllers
       /[...]
       /models
       /views

In my config.php file i have base_url set up:

Code:

$config['base_url'] = "http://wolserv.zapto.org/";

In views files i use:

Code:

<link rel="stylesheet" href="css/style.css" type="text/css" />
<img src="img/sp.gif" />

OK. When I enter on the page with url:

Code:

http://wolserv.zapto.org/

everything is OK, but if I enter with url:

Code:

http://wolserv.zapto.org/index.php/

CSS styles doesn't work and img's doesn't displayed.
If you want, you can visit my page and check it. Click "Wyślij" submit button on this page: http://wolserv.zapto.org/

How Can I resolve this problem?
