i m trying to merge two nice scripts together but somehow i m making something wrong =(

This is how i thought it should work:
Code:

    $(function () {
       var randomImages = ['./content/pp/img/2511_1_b.jpg','./content/pp/img/5178_1_b.jpg','./content/kameha/img/5744_1_b.jpg'];
      var rndNum = Math.ceil(Math.random() * randomImages.length);
        var img = new Image();
        $(img).load(function () {
            $(this).hide();
            $('#loader').removeClass('loading').append(this);
            $(this).fadeIn();
        }).error(function () {
            // notify the user that the image could not be loaded
        }).attr('src', '+ rndNum +' );
    });

it works as it should when i leave out the randomize function. So how do i go about adding the array of random pics in there without fucking it up?

oh ok Very Happy

> }).attr('src', '+ rndNum +' ); <

look closely ....

yeah ...

}).attr('src', rndNum );

^^ should do the trick, cause the rest looks ok Wink

I haven't tried it myself. If it doesn't work just post again and I'll take a deeper look Wink

Maybe then it works like this:
}).attr('src', randomImages[rndNum] );
(You know... number isn't exactly the source.)

Sorry to hijack the thread, but I have a question. I have regular HTML page with images, but I saw on some tutorial cool java thing where you can make sth like this http://cssglobe.com/lab/tooltip/02/

Can I just implement it in the existing layout?

Yep, pretty much. Look under main.js in page source.

woohoo!! Very Happy Thnx!!

EDIT: I have a problem :\

I have done as it said in the tutorial page, but I don't have little images which turn to big, I have Big images when rolled over give the same - big image... Plus I think that their main.js is not liking my style.css Sad Halp!

The jscript code is:

And mine is:

I have already put the images and jquery.js but it's not working as I would wish...

yeah, now it works! Had it like that before and it didnt work because i put it in ' '

The only thing odd now is, that it only works for two of the three test-images. I ll have to look into that now =)

thanx for reminding me, would have given up now otherwise Very Happy

You should use Math.floor(Math.random() * randomImages.length);

cause random goes from 0 to <1.

Well they do have 2 different images in code
Code:

<li><a href="3.jpg" class="preview"><img src="3s.jpg" alt="gallery thumbnail" /></a></li>

There is a 3.jpg and 3s.jpg, which probably means 3.jpg small and big version. So yes, you actually have to create thumbnails or specify image size in img tag to have smaller thumbnails.
