I'm fed up with Nikon's free Picture Project software crashing on my Mac every time I want to view a slide show and think it's about time to seek out a more stable alternative. Apple's own iPhoto is not an option.
I like what Picture Project offers: the ability to tag images with keywords; the tag mark and protect functions; the search filters, and the basic photo editing tools for when a minor tweak is all that's required.
It is rather clunky though, and slow when swapping between View and Edit functions, so something with a bit more oomph when handling files would be a blessing.
I've no idea how many photographs I have. At a guess, possibly somewhere between 4-8,000, maybe more (can't bring myself to consign images to the trash!).
