You use the imageData technique when you want to reduce the dimensions AND the filesize of an image (could also be called a "lossy" process because you lose data by using this method).
For example, say an 800x600 image runs 2MB. If you reduce the dimensions of the image and lock it, the image still occupies 2MB of memory, and can be restored to its original dimensions when unlocked. The imageData technique is similar to scaling an image in something like Photoshop or GIMP: you are removing imageData, the image will only occupy a few hundred K or less, and cannot be restored to its original size.
