Last night we spend some time organizing files (using the Finder) and photos (using iPhoto). In both cases I emphasized the importance of knowing what you want to move and where you want to put it. Knowing this you can open the proper windows with the files (that you want to move) and the folder (that is the target for the move).
This morning I found this video describing how to organize photos in iPhoto. I think it illustrates what we did. Notice that the author goes one step further by creating a folder and moving his albums into folders.
This could be helpful once you create many albums and want to organize them into manageable categories. – Happy Viewing
