Moving iPhoto Library

I have an old MacBook Pro that I am trying to clense before I take it to school for my students to use to edit movies and create videos. In the old days I used to be able to right click on photos and see the actual file of the photo so I could just copy the .jpg images to a hard drive or burn them on a disk or upload them to Flikr or even my Dropbox. With the new OS not so much. Can I mention that this is frustrating me to no end and now I don't erase my SD cards with old pictures after I upload them to iPhoto. Apple, please make this easier for those of us that do not want to copy and re-name our iPhoto libraries. Here is a video I found on YouTube, not my ideal solution! If you would rather have a southern accent watch here: I have successfully put my old pictures on an external hard drive now I can free up space on my old MacBook Pro so we can create some videos at school! Wishing you all a great school year!
