PHP image rotator help

[john010117]

I have used one of your scripts called "Random Image Rotator". It's supposed to display a random image every time you load up the page. I've inserted the code into a file named "rotate.php" and have changed the necessary variables to make it work. All my images are in the "images" folder, and I haven't placed this file in a folder. Here's the code for it:

[code]<?php
// Change the folder name to your one in the line below
$folder = "images";
srand( time() );
if ($directory = @opendir($folder)) {
while (($image = readdir($directory)) !== false) {
if ( eregi( '.(jpg|gif)$', $image ) ) { $images[] = $image; }
}
closedir($directory);
}
$image = $images[rand() % sizeof( $images )];
if ( eregi( '.jpg$', $image ) ) {
header( "Content-Type: image/jpeg" );
} else {
header( "Content-Type: image/gif" );
}
header( "Content-Length: " . filesize( $folder."/".$image ) );
readfile( $folder."/".$image );
?>[/code]

Can anybody detect what's wrong with this code? Note that the code didn't say anything about needing a MySQL database (which I don't have; I'm on a free hosting account).

If you must see the file which I've placed this code into, [url=http://free.hostultra.com/~halotrilogy/rotate.php]here it is[/url].

Thanks in advance.

Does your hosting support GD Library? And if so, make sure that it has support for the image type you're using.

Upload a file to your host and call it info.php....with the following code:

[code]<?php

phpinfo();

?>[/code]

Then bring up that page in your browser and check for GD Library.

I've saved the code like you told me to do, but I didn't see anything about GD Library... if you want to double-check, [url=http://free.hostultra.com/~halotrilogy/info.php]here's the link[/url].

PS: The code author said you only needed PHP, and nothing else.

The code posted doesnt need the GD lib. and pretty sure his host doesnt support it ><.

Just of curiosity where'd that code come from?  It looks familiar, not sure why though...

Edit:

Hmm just tested the posted script on my local server... Worked perfect.  On the page you posted a link to some javascript tag is appearing and I think thats messin with your headers and makin it output the page as text... Does your webhost automatically append that script to everypage?

Noticed the same thing. A lot of free hosts do this. Probably a popup/ad being called via Javascript.

[john010117]

I [i]do[/i] have 1 popup ad... is that why it isn't working?

[corbin]

Plainly put - yes.

Unless there is some way to get them to disable the popup on that page that script will not work.

An alternate method would be to generate the image name then call to it via a basic <img> tag...

[john0117]

Ok, thank you. I have just moved over to a different host with NO POPUP ADS. It's working perfectly. Thank you all very much.

Just of curiosity is it a free host with out pop-ups?  Cause if it is I would like to know what site it is :P
