The FTP pictures aren't updated.

Hello,

I'm building a website with wordpress and ipboard.

I customized the template of the ipboard forum, by changing the css files (working) and replacing pictures (don't work).
My website pictures don't refresh itself.

For example:

This one should be green (the blue isn't on the server anymore):
http://gdevhost.altervista.org/forum...ion/f_icon.png

This one was a test (the image that i want), i deleted the file f_icon1.png and it's still working..
http://gdevhost.altervista.org/forum...on/f_icon1.png

The only way that i see to resolve it, could be, to change the names and edit scripts, but i won't do that.

Somebody can help me to fix it ?
Thanks in advance.

I don't know how, but the bug has been fixed.
It's Solved
