pretty much useless

Look: Unbound is exactly what it claims to be—a fast, simple photo file management too—but that is it. Not an inch, not a millimeter more! You’re little better off than you would be if you created your own folders for your albums (eg Snake River 2014, Aunt Sara’s wedding, etc) and copied your photos to these. Better still you can do this in Dropbox or the equivalent. Unbound will do this for you, but you can’t order the photos except by date or file name, you can’t edit them (not even rotate an image), you can’t reduce the size and resolution (say for web browsing or sharing via text)…I could go on ad infinitum. Save your self $10 and just use the Finder and Preview or pay for a “grownup” photo management tool.
