Sure enough I found most of the problem right after posting. I was
repeating the comment[] setting part twice. It's still not updating with
a refreshed comment after changes though. I'll upload the latest version
(and probably figure it out in a minute<g>):

<?php
$imagedir = getcwd();
$key = 0;
$fh=opendir($imagedir);
# process folder
while ($file = readdir($fh)){
if (ereg('.jpg|.JPG.|.jpeg|.JPEG|.gif|.GIF|.png|.PNG', $file)){
$basename = substr($file, 0, (strrpos($file, ".jpg")));
if (file_exists ("$basename.txt")){
$comments[] = file_get_contents("$basename.txt");
} else {$comments[] = "";}
if (isset ($_POST["comment"])){
if ($key == $_POST["count"]){
$handle = fopen ("$basename.txt", "w");
$comment = stripslashes($_POST["comment"]);
fwrite($handle, $comment);
fclose ($handle);
unset ($_POST["comment"]);
}
}
$pic_name[] = $file;
$getimagesize[] = getimagesize($file);
$imagesize[] = $getimagesize[0][3];
unset ($getimagesize);
$key++;
}# if a jpeg
}# while read dir

###### begin printing #######
$cnt= 0;
while ($cnt < $key){
$image = $pic_name[$cnt];
$basename = substr($image, 0, (strrpos($image, ".jpg")));
print "<center><img src=\""
.$pic_name[$cnt]."\""
.$imagesize[$cnt]
." title=\"".$pic_name[$cnt]."\"";
print "\"><br></center>";
if (isset ($_POST["comment"])){
if ($cnt == $_POST["count"]){
$comment = $_POST["comment"];
}
} else {
$comment = $comments[$cnt];
}
print "<br>" . $comment. "<br><br>";
?>
<form method="post">
<input type="hidden" name="edit_comment">
<input type="hidden" name="count"
<?
print "value=\"" . $cnt . "\"";
?>
>
<button type="submit">edit comment</button>
</form>
<?
if (isset ($_POST["edit_comment"])){
if ($cnt == $_POST["count"]){
?>
<form method="post">
<?# <input type="hidden" name="edit_flag2">
?>
<input type="hidden" name="count"
<?
print "value=\"" . $cnt . "\"";
?>
<textarea name="comment" ROWS=6 COLS=60>
<?
if (isset ($comment)){
print $comment;
}
?>
</textarea><br>
<button type="submit">submit changes</button>
</form>
<?php
unset ($_POST["edit_comment"]);
unset ($_POST["count"]);
}# if count matches
}# gather new comments
$cnt++;
} # end foreach processing image
?>
