I need to add all the old image IDs / associated tags to new table

Answer 1

If i am not wrong you want to add old table record to new table.

So all you need to do is query old table and explode imgid and loop through exploded string and add it in new table.

Sample Code.

<?php

    $query = mysqli_query("SELECT * FROM oldTable")or die(mysqli_error());
    while($row = mysql_fetch_assoc($query))
    {
        $ids = explode(",",$row['imageID']);

        foreach($ids as $newImgId)
        {
            $Insert_query = mysqli_query("INSERT INTO NEWTABLE ('tagname','img_id') VALUES ('".$row['tag']."','".$newImgId."')")or die(mysqli_error());
        }
    }
