If you have bookmarked something from the older layout, when you click on your bookmark you will get a 404 Not Found notice. To refind your item on the new layout, just enter the stock number in the search bar, and click - if we still have the item, this will bring it up. Stock numbers are the digits in front of the / in your bookmark - for example either /c15698pix or maybe photos/c15698. Stock number are either plain digits, or may be preceeded by a 'c' or an 'e' or an 'm'.
Happy hunting!
