Random Image Generator

this isn't really a tutorial, but I couldn't find out a place to post it. So here it goes. I originally wrote this script in Javascript, but than my friend later ported it to PHP and I just kept it. Made some minor changes to it though.

Code:

---

<?php

 $gen = rand(1,5); //change last number to number of images you have
 print("<img src="dir/to/imgs/splash$gen.jpg">");

?>

---

okay, um place this script within the body tags of your layout. Change "dir/to/imgs" to the directory that houses your image. Re-name all your images to splash1.jpg, splash2.jpg, splash3.jpg, etc. All the way up to the last number you put in "rand(1,5)".

I have tried this script and it seems to work just fine. Just reply if you encounter a problem.

Thanks for this, im gonna be starting to learn php soon. Will come in handy.

no problem. happy to help, thats what coders are for :P :D

Does it work here? I know I've tried a CGI script for this and it told me that it doesn't allow dynamic url or something along that line... :(

yes, it works. Im not too fond of CGI, so I dont know what could have gone wrong. I've used this script numerous times before, and it works just fine.

and where should i write in code, where i wanna show the picture?

Code:

---

print("<img src="dir/to/imgs/splash$gen.jpg">");

---

wont work... must be like:

Code:

---

print("<img src=\"dir/to/imgs/splash$gen.jpg\">");

---

oh lol... PHP isn't hard to learn, of course my first language was C++...

That ain`t Image generator. That`s just script, that shows random image of premade ones.

Image generator is something that actually generates an image with GD library, not just gives a random filename in <IMG> tag.

So don`t worry about dynamic url - you can`t find it here.

i agree. this isn&#39;t really a generator or anything, its just a random image show-er. this could help early coders though.

wouldn&#39;t it be better to use something like this:

Code:

---

<?
$random_image = array("http://www.site.com/image.jpg","http://www.site.com/image.gif","http://www.site.com/image.bmp","http://www.site.com/image.png","http://www.site.com/image.tga");

$images = count($random_image);
$random = (rand()%$images);
print"<img src=\"$random_image[$random]\" border=\"0\">";
?>

---

then you can add images to the array without having to editing the rest of the script for things like image name changes etc
