I need a widget that will display a random photo each time pages is loaded.

Anybody know how to do this in Xara ? Put a photo in a box on a page. Each time the user lands on the page a different photo is displayed in that spot. Even a reload/refresh page triggers it. On Display. It can be either a random pick or one in a specific sequence. I've found places on the internet that show how to code this, but I don't know php or whether php will work with Xara.

I think this can be done with a script. Check back and see if one of our members can suggest one.

Hi,

you could find a widget, but I would do it as follows:-

Create a php file called random.php in your root folder (where index.htm is), here is the code for it:-

<?php
// RANDOM IMAGE SERVER by Sculptex
// www.sculptex.co.uk
// Demo @ random.prevoo.uk

$path = "random/";
$files = array_diff(scandir($path), array('..', '.'));
$imgs = array();
$i = 0;
foreach($files as $file) {
$imgs[]= $file;
$i++;
}
$img = $imgs[rand(0,$i-1)];

$file_extension = strtolower(substr(strrchr($img,"."),1));
switch( $file_extension ) {
case "gif": $ctype="image/gif"; break;
case "png": $ctype="image/png"; break;
case "jpeg":
case "jpg": $ctype="image/jpeg"; break;
default:
}
header("Content-type: " . $ctype);
header("Expires: ". date("r",time() + (1)));
readfile($path.$img);
?>

Create a folder called random
Fill folder with required images
Create placeholder on your website and insert

<img src='random.php'>

You can see it in action at http://random.prevoo.uk

I see on the example web site that every image must be the same size and aspect ratio. Is it possible to vary these in size and aspect ratio?

I followed your instruction to the letter Sculptex but I can only get a missing image icon.
