given two text files, one with a list of image paths and names based on
webroot, the other with a list of captions, so that 7th caption in the
caption file goes with the 7th url in the images file, and images and
captions are each listed on a single line in their respective files:

<?php

$flags = FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES;

$captions = file("captionfile",$flags); // read array of captions, 1 per
line
$images = file("imagesfile", $flags); // read array of filenames, 1 per
line

$index = rand(0, count($captions)-1); // get a random index

$imgfile = $images[$index];
if (strpos($mgfile,"/")!==0) $imgfile = "/" . $imgfile;
$captiontext = ucwords($captions[$index]);

echo <<<EOT

<p style="text-align:center;margin:0 auto">
<img src="http://www.myhost.domain{imgfile}" alt="{$captiontext}"><br>
{$captiontext}</p>

EOT;

?>

imagesfile might contain:

---8<--- cut here ---8<---
/dir/dir/myface.jpg
/dir2/clown.jpg

lorry.png

/dir/dir3/cat.gif
/dir/dir3/dog.gif

---8<--- cut here ---8<---

captionfile might contain:

---8<--- cut here ---8<---

a mugshot, so if you see me you'll know me
my clown face
the lorry I drive

my pet cat

the dog next door
---8<--- cut here ---8<---
