For some reason, Lightroom sometimes labels images as missing when they’re not. They show up in Windows Explorer (or Apple Finder) at their correct location.

To fix this, select the incorrectly labeled photos and remove them from Lightroom’s library.

After that, you can simply import them again (Import photos at their current location), and Lightroom will no longer label them as missing.

Please note that you’ll need to double check that these photos are indeed where they are supposed to be before removing them from Lightroom library. If they are truly missing, they may need to be retrieved from back up.

Also note, that if these images were previously part of a collection, they may have been deleted from these collections.

So here we have a 292 page book about usability without bookmarked chapters or sections. Bookmarks are among the most useful features in a PDF. It is charming that the publishers think highly of those in our industry: they must think we’re all monkeys with big brains and good memories…

Great initiative: the PHP community is pushing for upgrade to v5. It certainly is about time.
