The first is if the drive on which the pictures are kept is 'Offline' i.e. it's an external hard drive or network attached. If you reconnect the drive and then come out of the image you are in look at something else, go back and all should be well.
The second way this problem might occur is if you have moved images or changed folder structures using something other than Lightroom. You should avoid doing this, but if you have not all is lost as long as you can find the image on your hard drive. Doing this the locate trick will re-map that image and any others where the same path issue exists.
If you right click on an image there is an option that states 'Show in Explorer' that shows you where the image was meant to be and is a good place to start. You can use the windows search for file function and put in the file name (which you can see in Lightroom). Most times find one and the rest will sort themselves out unless you have done a major restructure outside of Lightroom.
If you want to move images around best way is drag and drop in the Lightroom File structure, this will keep everything mapped.
