Display of Extra Product Images

Hi there,

I've got a little problem with how my site is displaying the extra images of a product. Rather than having them side by side they are getting wrapped onto the next line. An example of this can be seen here http://www.wargamesheaven.co.uk/index.php?main_page=product_info&cPath=4_29_187&products_id=2750 where the two images at the bottom should be on the same row. I should point out that this always happens to the last image in the row, for example the third one of three or the third and sixth of six.

I used to have a similar problem with the display of products in the main category page and I fixed that by changing the code from $col_width = floor(100/$num_categories); to $col_width = floor(90/$num_categories); in the files category_row.php and new_products.php.

I would like to apply the same mod for this problem but I don't know what file I need to edit to apply this change to the layout of the extra images? Can anyone please tell which file to change?

Thanks very much for any help
Guy
