Very nifty Brad,
One addition though, so she/you can work back from any point:
<MoreUntestedCode>
$i = 0;
$start = strtotime("2006-10-05 12:05am");
while(count($img_array) < 5) {
$year = date("Y", strtotime("-$i minutes", $start));
$month= date("m", strtotime("-$i minutes", $start));
$day = date("d", strtotime("-$i minutes", $start));
$hour = date("H", strtotime("-$i minutes", $start));
$hhmm = date("Hi", strtotime("-$i minutes", $start));
$filename = "file.$hhmm.jpg";
if(file_exists("/path/to/$year/$month/$day/$hour/$filename")) {
$img_array[] = $filename;
}
$i++;
}
print_r($img_array);

Small, minor, insignificant point.... If I have less than 5 files this
loop will never end. But you all knew that right?
Also, depending on the frequency of files (i.e. are there months-worth
of gaps or minutes at most), the following might be faster...
* glob the files in the first dir
* binary chop to find the nearest to your start time
* go back in the array from that point to find your 5
* if you hit the start of the array, go down a day, repeat the glob and
start from the end of the new array
