I want to output an img url from a random image script

Enterprise

I've been googling this for literally two hours, and finding nothing that is exactly what I need. Forgive me , but I'm unfamiliar with PHP, so there's just no way I can do this myself. If you know of a tutorial that explains what I need, please point me in that direction, if you don't want to explain it to me yourself.

What I need is this: I want to generate an image url that I can display on any webpage that will display a random image from a directory. I've found numerous scripts on how to create the random image, and I've done that, but I don't know where to go from here, or if I'm even in the right direction at all.

Please help!

I guess what I'm looking for is one url, like turn 4 .pngs into one .png file. Does that make sense? Sorry, I'm really bad at describing things since I'm totally new to PHP.

Then read PHP GD Library tutorials - it's Image manipulation lib for PHP Smile

There are a lot of tutorials on web ...
In short - it will be few steps:
1. Ceate blank, big png
2. Read 1st png and paste it in upper left
3. Read 2nd png an paste in in upper right
4. ... bottom left
5. ... bottom right
6. Save/output to browser the new created png file

To get all the images in a dir (easier than having to rename the images and editing the script everytime you add one):
http://us.php.net/manual/en/function.readdir.php

To make one image from multiple images you need GD like b4r4t said.

To get one image (a random one):
http://us.php.net/manual/en/function.array-rand.php <-- use that on an array you make with readdir()
http://us.php.net/manual/en/function.fpassthru.php <-- use that to output the image to the browser (don't forget to set the headers)
