Random Image · Mar 13, 20:42 by Shannon Wynter

Ok, one of the most requests I get is a script for random signature images.

The second most frequent request I get is for random avatar images

Well lets cover the first one

As always this script can be downloaded here

Note for internode customers: if you’re using your node space it’s important to chmod 0755 you’ll need to check with your ftp client on how to do this. If you don’t you will get an ‘Internal Server Error’

One tip I can give you tho is to use the console ftp client included with windows to chmod after you’ve uploaded the file.

Example for Internode users

1. Go Start/Run
2. Enter: ftp users.on.net
3. Log in with your username/password
4. cd /pathtoscript/
5. lit site chmod 0755 randomimage.php

That should fix your ‘Internal Server Error’

5. Due to the large number of requests I get for
6. this (and similar) script, I'm making it availible
7. for all to see and use
8.  
9. Configuration Options:
10. $PathToImages = The path to your image files
11. Example:
12. $PathToImages = "images/"
13. */
14.  
15. $PathToImages='images/';
16.  
17. // !!!!! Don't edit below here or I won't smack you.!!!!!
18.  
19. // Open a directory object
20. $Dir = dir($PathToImages) or die("Oops, it's broken - are you sure you've got the right PathToImages?\n");
21. // Read the dir
22. while (false !== ($DirEntry = $Dir->read())) {
23. // Look for images
24. if (preg_match('/\.(jpe?g|gif|png)$/',$DirEntry)) {
25.   // Keep track of the images we've found
26.   $Images[] = $DirEntry;
27. }
28. }
29.  
30. // Get a random image
31. $Image = $Images[array_rand($Images,1)];
32.  
33. if ($fp = fopen("$PathToImages/$Image",'rb')) {
34. // Helps to know how big the file is we want to read
35. $FileSize = filesize("$PathToImages/$Image");
36.   
37. // Get the file extension
38. preg_match('/\.(jpe?g|gif|png)$/',strtolower($Image),$Match);
39.  
40. // Work out what our content type is
41. if (in_array($Match[1],array('jpg','jpeg'))) {
42.   $ContentType = 'image/jpeg';
43. } elseif (in_array($Match[1],array('gif','png'))) {
44.   $ContentType = 'image/'.$Match[1];
45. }
46.  
47. // Print out some headers to satisfy the browsers
48. header("Content-type: $ContentType");
49. header("Content-length: $FileSize");
50.  
51. // Print out some headers to keep the random image from being cached
52. header("Cache-Control: no-cache, must-revalidate");
53. header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
54.  
55. // Output our image (Long process huh)
56. print fread($fp,$FileSize);
57.  
58. // Always clean up after yourself
59. fclose($fp);
60. }
61. ?>

Now to make it work as an avatar you need to trick apache into serving up your php script as a jpg/gif or png file due to the way the forums limit the extensions on files.

Best way to use this file is to make it htaccess.txt on your windows machine, upload it, then rename it to .htaccess

1. RewriteEngine on
2.  
3. RewriteRule randomimage.jpg /~<YOUR USERNAME>/<PATH>/randomimage.php [L]
