Scrolling information no longer showing ???

Question

i had my photos organised into folders and so when scrolling through the iphoto library the folder name )scrolling information) would appear as i come across the photos from a specific folder,
i recently added pictures to one of those folders manually and now the scrolling info doesnt appear anymore, when i added them i simply dragged them into their folder in the iphoto library folder in the pictures folder and then to make them show in iphoto i also imported them to the library
im guessing something wrong about the way i done this had an effect on the scrolling information which doesnt show anymore
sorry if this sounds confusing

FYI re: Finder folders, Film Rolls, Albums, and Keywords
The library folders you see in Finder reflect the Film Rolls in iPhoto. Try viewing your library in film roll view (View > Sort Photos > by Film Roll). Yes, each time you import one or more photos it will appear in your library as a new film roll. But you can change that (only after importing). Highlight the new roll name and icon, then drag it up to the roll with your car pictures until that roll name becomes selected, then drop. Your new roll is gone, but those pictures are now located inside the other roll. Roll info can also be edited in the info pane when you select a roll in the iPhoto window. Retitling and reorganizing film rolls in iPhoto will be reflected in the folders you see in Finder.
When you view your entire Library in film roll view, you are seeing your iPhoto inventory; that is, each photo in your library displays once and only once. I keep my inventory organized chronologically and by camera. (Separate rolls for pics from my digital camera vs. a disposable camera vs. my kid's camera....) Once my rolls are organized I don't change them around. I don't organize my rolls by subject because there are ways to do this in iPhoto that allow for total flexibility.
Albums, as Terence described, are another level of organization which allow photos to be categorized in multiple groups. Albums do not duplicate your photos; they instruct iPhoto as to which photos to display together. Smart albums are particularly flexible, because they will find the pictures that match your criteria and will continue to change as you add more pictures that match the criteria.
If you assign keywords to your photos you can find pics by subject with a single click. Add a keyword "car" to your list. Select all photos in your library with your car and drag them to the "car" keyword. Then by simply clicking the keyword you will pull up all of those photos. This is very powerful when you assign multiple keywords and use them in combinations. It makes your smart albums more flexible and powerful, as well.
With all this flexibility, how you organize your photos is up to you. Just never, ever do it from the Finder.
