Random PHP image

[Takara]

Hi there,

I want to be able to call am image using a php script (so, <img src="random.php">).. but as you see, it has to be random. I dont have access to GD (its a windows box, plus all the GD dlls ive tried just gave me errors).

Basically I just need it to read from a file, a random image name and use it. This is what I've come up with so far:

<?
header("Content-type:  image/gif"); 
passthru("type //gota be random here//"); 
?>

hehe. Ive tried doing some stuff, but the headers always get sent before the image one.. so it doesnt work can you help?

thanks ^_^

If you are using a mysql database here is something to play with.

<?
$user="usename to login";
$password="password to login";
$database = "your database";
$table = "your table";

  mysql_connect("localhost","$user","$password")or die ("no mysql connection");
  mysql_select_db("$database") or die ("Could not get database<p>");
 $result = mysql_query("select * from $table order by rand() limit 1") or die ("error:".mysql_error());
  while ($row=mysql_fetch_array($result))
  {
        $image=($row['image']);
        $image = "img_dir/$image";
        print "$image";
  }
?>

untested Quikie Code:

<?php

header("Content-type:  image/gif");

// list all gifs
$dir = `dir /b *.gif`;
// split it into an array
$dir = explode("\n", $dir);

// seed the rand()
srand((double)microtime()*1000000);
// pull a random image
$i = rand(0, count($dir)-1);

// print it
passthru("type " . $dir[$i]);

?>

Thanks both of you, both of them are great for what im doing

But one other question (actually two)... how can I grab the contents of a text file and overlay it over a transparent gif(or png)?

I may need GD for it, so do you know where I can get a good windows GD dll?

[Mark Hensler]

You will need some kind of GD library. Maybe ImageMagik (I've never played with it).

I have no idea where to get this stuff for Windows.

[Takara]

well, I grabed ImageMagik.. but it seems the only program it lets me use in there is mogrify, and It doesnt even seem to do the operations when I tell it to >_<

if you downloaded php with exstentions for win32 box, you will be able to run GD. it has all the files you need.

[Takara]

Dont you have to compile the 4mb version though? Im not sure how to do that

[scoutt]

no you download the one for windows which is in zip format I think. don't have to compile anything.

[Takara]

Thanks very much. I did it and got it all running. I even got the GD image I wanted to work! Im going to start playing with all these new extentions

Thanks again
