Hi,

i have a picture which dissapeares via Effect.Fade, but i’d like it to  
be seen when you leave the site and come back.  
but this doesn’t work out when the back button is used, as the site is  
not reloaded then and the div with the picture is still set on not  
visible/opacity=0

is there any possibility or solution?

thanks,  
judith

You want AJAX history.

Basically you set some javascript to fire when the person comes back  
to the page.

Check out

for how to do it.

Judith, this sure looks like a question about Ruby on Rails, but this is  
the Ruby mailing list. You’re going to have better luck getting an  
answer on the Ruby on Rails mailing list. See  
[Ruby on Rails — Community](http://www.rubyonrails.com/community).
