Avtar

[hjpotter92]

There is another topic for it but I didn't found it for three pages so I created it. I wanted to ask that I got a news about the avtars being changed everytime you refresh your page. It has a bit of coding. So what is it? Is it right that the avtars do change on their own?

[praka123]

did u meant GIF?

[hjpotter92]

Of course not It is only a bit of Image Ready. I am saying about coding. It is I think to be some special coding. I hope i didn't misread.

[Krazzy Warrior]

do u mean for Animation ?
Write clearly.

Yes,it must be a PHP script. as for the link it doesn't open forme. I don't know the reason.

^But you can't do it on this forum because the avatar manager downloads the remote image to the server and serves the avatar from there!

[hjpotter92]

OMG, it is really a problem forme then. But stil the coding would help me a lot.

Latest version always at:

*/// Make this the relative path to the images, like "../img" or "random/images/".
// If the images are in the same directory, leave it blank.
$folder = '';

// Space seperated list of extensions, you probably won't have to change this.
$exts = 'jpg jpeg png gif';

$files = array(); $i = -1; // Initialize some variables
if ('' == $folder) $folder = './';

$handle = opendir($folder);
$exts = explode(' ', $exts);
while (false !== ($file = readdir($handle))) {
foreach($exts as $ext) { // for each extension check the extension
if (preg_match('/\.'.$ext.'$/i', $file, $test)) { // faster than ereg, case insensitive
$files[] = $file; // it’s good
++$i;
}
}
}
closedir($handle); // We’re not using it anymore
mt_srand((double)microtime()*1000000); // seed for PHP < 4.2
$rand = mt_rand(0, $i); // $i was incremented as we went along

header('Location: '.$folder.$files[$rand]); // Voila!
?>

Usage:

For the simplest possible installation, just drop this code in a directory with the images you want to rotate, and call it like you would a normal image, for example:

<img src="/dropbox/2003/rotate/rotate.php" alt="A Random Image" />

But how would I load it as AVTAR on to my account? <_>

[QwertyManiac]

I do not know, look into your forum's avatar mechanisms probably and modify them as you wish.

[hjpotter92]

OKI got it. Now look at it:

[dheeraj_kumar]

I want to ask about a similar thing... check this out...



the link is http://chandras.com.au/x0r/randomimage.png, ends in a png extention. how about that?

ps: reload the image to get different images

[victor_rambo]

^Its the same thing as CAPTCHA except for the background!

[QwertyManiac]

Yes it serves a random image every request I suppose.

[dheeraj_kumar]

Ok, so is it possible to do it in a wordpress blog? Any script to randomize images every request?

[hjpotter92]

It only changes the color but doesn't like the one JOHN BEAK has done.

isn't it just a mapping ?

like we do in JSP

[dheeraj_kumar]

Rohan, can you tell us how to do it in wordpress blog?

[victor_rambo]

There is actually no need to modify any WP files for that. You can do that with javascript too, but I will discuss here how its done with PHP:

There is actually no need to modify any WP files for that. You can do that with javascript too, but I will discuss here how its done with PHP:

PHP Code:

//put names of all images you want to rotate randomly
$image_set=array("img1.jpg","img2.jpg","img3.jpg","img4.jpg");

//now select any one random image
$randomly_selected_image=$image_set[array_rand($image_set,1)];

//now fetch the image and store it in a string
$image=file_get_contents("images/$randomly_selected_image");

//send a header to the browser telling it that we are now sending an image
header("Content-type: image/jpg");

//now send the image. 
echo $image;

/*
Because we informed the browser earlier that we are sending an image, it could parse that string as an image.
Else it gets confused and parses it as plain text which looks horrible(with all question marks and rhombuses and weird characters-like the one when fonts are missing!)
*/ 


Now you can save this file as randomimage.php on yourserver. The HTML markup for your posts would be

<img src="randomimage.php" alt="random image" title="This image has been generated randomly and will change on refreshing">

Thats how simple it is!

[hjpotter92]

Yeah! it is ismple for those who know something about PHP script not me.
