I figured what was wrong. I don't know if how I got it working matches the original code or not but it works.
Here's what I needed to do.

in pppanel.php, find:

while ( $thisphoto = $DB_site->fetch_array($myphotos) ) {

under that, put:

$theext = get_ext( $thisphoto['bigimage'] );

next, find:

if ( $medsize > 0 ) $imgurl = "{$data_dir}/$ppcat/{$user}{$photo_name}-med{$theext}";
        else $imgurl = "{$data_dir}/$ppcat/{$user}{$photo}"; 
                
        $mthumb = "<img border=\"0\" src=\"{$data_dir}/{$ppcat}/thumbs/$photo\" alt=\"\" />";

and replace with:

To make clickable thumbnails in posts

if ( $medsize > 0 ) $imgurl = "[*url={$data_dir}/$ppcat/{$user}{$photo}][img]{$data_dir}/$ppcat/{$user}{$photo_name}-thumb{$theext}[/img][/url*]";
        else $imgurl = ""; 
                
        $mthumb = "<img border=\"1\" src=\"{$data_dir}/{$ppcat}/$user$photo_name-thumb$theext\" alt=\"\" />";

(Removing the * in the [*url][/url*]

And need to change the template,
Find:

opener.document.vbform.message.value = BodyVal + '[img]' + UBBCode + '[/img]';

replace with:

opener.document.vbform.message.value = BodyVal + UBBCode;

Or if you want to have space between the thumbs, replace with this:

opener.document.vbform.message.value = BodyVal + UBBCode + ' ';

or:

To place medium images in the post or full sized if medium not available

if ( $medsize > 0 ) $imgurl = "[img]{$data_dir}/$ppcat/{$user}{$photo_name}-med{$theext}[/img]";
        else $imgurl = ""; 
                
        $mthumb = "<img border=\"1\" src=\"{$data_dir}/{$ppcat}/$user$photo_name-thumb$theext\" alt=\"\" />";

If your DB's are separate but have the same password, change the FROM pp_photos in the query.

$query = "SELECT id,cat,title,bigimage,medsize FROM pp_photos WHERE userid ='{$user}' AND storecat=0 ORDER BY date DESC LIMIT $page,16";

to FROM databasename.photos so it looks sort of like this:

$query = "SELECT id,cat,title,bigimage,medsize FROM databasename.photos WHERE userid ='{$user}' AND storecat=0 ORDER BY date DESC LIMIT $page,16";

(Changing the databasename to match what your PP database name is)

Side note.. I had to include the [*img][*/img] tags in the code to get them to input if you get two sets, remove the ones inthe aove codes.
