Random Image on WebPage

cxjtc — Tue, 07 Feb 2012 19:25:49 +0000

I was doing the home page of my site today and couldnt decide which image to put there. So I got a bunch of them and set it to show a random image on page load. Heres how I did it:

first create a directory in which you want to put your images:

$ mkdir frontcycle

then put all your pics in that folder.

$ cp pic1.jpg frontcycle/

next you write a php function. you can do this in an external page or right in your file.

function get_random_image() { $dh = opendir( "path/to/frontcycle" );


   $files = array();
   while ( $file = readdir( $dh ) ) {

      if ( preg_match( "/\.(jpg|jpeg|gif|png)$/i", $file ) ) {

         // add or remove file extensions if you want

         $files[] = $file;

      }

   }

return $files[ rand( 0, sizeof( $files ) - 1 ) ]; }

finally, in the page your image will be displayed, add the following code:

' />

Copy/Paste from XTerm

Users of XTerm know all too well the frustrations caused by the inability to copy something in XTerm and paste it somewhere else, and vice versa. You can hack and recompile XTerm to solve this problem, but heres a way enable copy/paste as you launch:

/usr/bin/xterm -xrm 'XTerm*VT100.translations: #override : select-end(PRIMARY, CLIPBOARD, CUT_BUFFER0)' -e 'ssh user@server'

// basic information $to = "mailbox@jenpeters.com";


$from = "noreply@jenpeters.com";
$subject = "This is an email";
$body = "This is some text";
// get file information

$file = "/home/cxjtc/file.csv";
$filename = basename( $file );
$contenttype = "text/csv"; // change to suit your attachment
$fh = fopen( $file, "r" );
$content = fread( $fh, filesize( $file ) );
fclose( $fh );
$content = chunk_split( base64_encode( $content) );
$headers = <<
