today i opened Lightroom 5.7 and a lot of pictures were shown in low quality (20 * 30 pixels) because Lightroom could´t find these files. They are all saved on my Macintosh HD, my intern hard disk.
A few weeks ago i imported them in from Aperture into Lightroom; Aperture can find every file, but it does´t work with Lightroom.
The software on my mac ist OS X 10.9.5.
Can you help me?
You have most likely moved them outside Lightroom.
Click the exclamation mark on on one of the thumbnails, and point LR to the folder where they now reside.
Click the exclamation mark
That shoild be question mark
