Off the top of my head the file itself is not too terribly different than the original if I remember right. Basically it is only minor changes like making that right td another table so we add in </tr><tr> to print it in another row and then we wrap the 2 boxes in a table with 3 different td's one for each table with a width of a third.
You should be fine to use it with 8.23 since it was made from an 8.22 template.
Probally the only difference would be the photo title is not bold now it is h1 for
seo googling purposes.
