When I bought a Mac Mini with Mac OS X, I could show image dimensions in the Get Info dialog.

After that, I installed some mobile application development software and later I noticed, Get Info was not showing the image dimensions anymore. I need to check the dimensions of those images to include artwork in my project. Now, I reinstalled my Mac OS X and it's working fine – it is showing the dimensions:

Before that, 516x314 was missing. Why did that happen? How can I prevent it from happening again?

It would really help if you told us what mobile application development software you installed. – slhck Nov 4 '12 at 10:41
I installed Xcode 4.2, Eclipse Juno and Source Tree for tracking git ang Git too. – Dinesh Raja Nov 4 '12 at 11:16
Hm. That shouldn't have caused anything, actually, but knowing whether it's the combination of these apps or just a single one would help. Have you reinstalled all of them again? I guess it was just a hiccup from Spotlight. Maybe restarting and reindexing Spotlight would have helped. – slhck Nov 4 '12 at 12:59
Were the files excluded from the Spotlight index? – user495470 Nov 4 '12 at 17:13
I'm facing the same problem too .. but I noticed something, if I check an image's info I get the resolution , but if I close that and check again the resolution disappears :s , so I can only check it once >.< – JiMMaR Jan 24 '13 at 12:44

The dimensions (and other metadata) of a file are stored in the Spotlight index, which allows you to effectively search for specific features. If the image dimensions are not available, this is likely caused by the files not being indexed, or the index being broken.

To solve this, try the following:

  • In any case, check System Preferences » Spotlight » Privacy. Is any folder containing these images listed there? If yes, remove it from the list.

  • To force-reindex Spotlight, you can just add your entire hard drive to this Privacy list, and immediately remove it again.

Now I don't have issues as I said. If I got any issues like that, then I will do as you said. Thank You so much:-) – Dinesh Raja Nov 6 '12 at 4:27
