Delete mutiple image with custom trigger

Question

I am attempting to delete multiple images associated with a record being deleted. The record has a field with the default filename, then each image has a prefix ("thumb_", "callout_", "feature_") along with this filename.
My issue is two-fold. I am attempting this with a custom trigger (on the delete record; using AFTER), but I keep getting an error message when I try to pull in the filename using tNG->getColumnValue(). The error reads:
tNG_fields.getColumnValue:
Column file is not part of the current transaction.
Here is my code:
$file = $tNG->getColumnValue('file');
deleteFileAndThumbs($file);
My second issue is in regards to the redirect after the triggers.
getPrimaryKeyValue() works just fine. Thus, if I change the image names to correspond to my record's "id" #, it will pull the ID # just fine. It will make it through my code and redirect back to the listing page. However, the images will not be deleted. If I remove the redirect, the images delete, but it just sits on this page. So I assume my issue is a result of the page redirecting before al the images are deleted. Is there a way to not allow the redirect to run until my deleteImages function is completed?
Thanks!

Ok. How about executing a SELECT inside a Custom Trigger and accessing
the resulting rows to use in PHP code also in the trigger?
Example - within the Custom Trigger execute:
$sql="SELECT * FROM table";
How do I execute it? With the regular DW code like:
mysql_select_db($database_conWV, $conWV);
$sql="SELECT * FROM table";
$result = mysql_query($sql, $conWV) or die(mysql_error());
$row_result = mysql_fetch_assoc($result);
$totalRows_result = mysql_num_rows($result);
or with some ADDT code like:
$result = $tNG->connection->execute($sql);
If I do the "ADDT" way, how do I access the rows?
$result['column'] or something?
