It just changed the product_info page,. specifically the product image. So, say, if I want to view the cover of X dvd larger,. I can simply click on it to do so. If it doesn't work, I have no clue how to fix it, mate. I can say that I did try using a contribution that included OS commerce and a some other contributions, like sts template, and it didn't work. I had to do a clean install of OS Commerce, just itself, then manually add the other contributions.
