How do I delete images in Finder's "all my Files" when I have the same pictures in a file in Documents? It seems like a lot of duplication. If I delete the individual image it disappears in the folder. Thank You.

All My files is a "search folder"

it isn't real storage location. All files within your home folder are found by the criteria set for the search folder and displayed to you In one place.

If the folder doesn't meet your needs, remove it from the sidebar.

that is the default set up for the finder window you are looking at You can adjust how ur finder widow looks when it is opened. Finder>Prefernces will give u the options as to how your finder window is displayed as default.

Hope this helps.
