An image randomizer that doesn't mess up your whole page?

[Ivy Newton]

Ya see, I'm trying to put an image randomizer on this webpage I'm making for a school project. But the ones I found online failed. The first one (in PHP) literally killed my webbie (though I think it's partially my own stupidity that did it) and I had to scramble and rename multiple files to get it fixed, and the second one (in Javascript) messed up the layout quite a bit.

Anyone have a reliable image randomizer script?

I see "dreamweaver" in the tags and have to say that that is probably the problem. :/

As in Dreamweaver doesn't support image randomizers? Or as in the layout is usually messed up in Dreamweaver's preview screen?

Well, it doesn't matter cause I finally found one. Somewhere.

What language do you want it to be in?

postninjaed: Dreamweaver is horrible, I suggest you get a text editor. They can work wonders.
And it is impossible to not support an image randomizer.

Actually I use Dreamweaver as I would a text editor, but the point of the class is partially that I learn Dreamweaver, so I'm kinda stuck with it.

Are Javascript or PHP ones better?
I managed to find a working Javascript one, but if PHP is better and you have the code (and step by step instructions, cause i managed to kill my webbie with the last PHP one I tried), then I'll consider it.

Dreamweaver preview wouldn't work with PHP because you don't have PHP installed, most likely. Agreeing with the above: if you're serious about this, get a good text editor. Anything more only drags you down.

eta: as for which is better, well, depends. Javascript is client side, which means you don't have to worry about support, but people do browse with it switched off; PHP (is terrible) is server-side, so you'd need hosting that supports it, although in the long run it is probably more flexible.

This is really a simple randomizer script; I could write up one myself. Of course, this assumes you know basic PHP.

So, make a list of the directions to the image files. Put them into an array by doing the following:

$imagelist = array("imageone.ext", "imagetwo.ext", "imagethree.ext", "etc.ext");

Obviously, replace the psuedonames with your own. Then, for the random part:

$result = $imglist[rand(0,sizeof($imglist))];

Of course, you can name the variables whatever you'd like, but this is for the sake of example. Now, putting it in the actual web page:

<img src="<?php echo $result; ?>" />

This should make an image tag with the random image's directory and/or filename with it, correctly displaying the image.
Also, make sure the first two code blocks are actually within "<?php" and "?>" tags, or else it would be interpreted as the HTML of the page.

edit: if you need a JS one, just ask.

Thankies for all the info~
I should probably find out about hosting and if PHP is installed and stuff...
That's probably pretty important.

With the PHP one I tried it wasn't that the layout didn't work, it was that I couldn't preview it in a browser at all. I think I majorly messed something up cause I'm still pretty unfamiliar with Dreamweaver and it was making me do something with something or other that I didn't understand. Heh.

Edit: And if I ever make my own site (read: not a school project) I probably will just use a text editor. I actually rather like doing my coding with Notepad, even.

Notepad sucks. Badly.

there's also Cream if regular ol' Vim is a little too thorny for you

$imglist[rand(0,sizeof($imglist))];

That's what array_rand() is for.
