i hv solved my problem. this will do
jz follow the instruction at the link above. my mbp started giving problem after i upgraded it from OS Leopard to OS Lion.
Let my summarize what i've done to make it work
1. Go to Disk Utility application. if u never knew bout this app jz find it in Spotlight
2. Select your Mac OS X startup volume in the column on the left of the Disk Utility window.
3. Click the First Aid tab.
4. Click the Repair Disk Permissions button.
it may take few minutes to complete. it's working fine with my mbp
I have the same problem but it is an external drive.
Oddly jpeg files will open initially but if I stay on the drive for any length of time I get the error message "The file waterhouse.jpeg couldn't be opened because you don't have permission to view it."
Following the instructions above is of no use as the 'Verify Disk Permissions' & 'Repair Disks Permissions' buttons are greyed out and therefore unselectable. The 'Verify / Repair Disk' buttons work but running them has not remedied the situation.
Can anyone assist? Cheers.

Select the external drive icon, then from the Finder menu > Get Info and find and check "Ignore ownership on this volume."
Basically everyone will own the files on the drive now, not to be used with backup drives or clones.
Back up all data. Quit Preview if it's running.
Hold down the option key and select Go ▹ Library from the Finder menu bar. From the Library folder, delete the following items, if they exist:
- Saved Application State/com.apple.Preview.savedState
Launch the application and test.
I had this problem too. I couldn't open several jpegs in Preview (tho they opened fine in Photoshop) and got that annoying "you don't have permission to view it" message for all of them. I followed the advice of "Mr Z. Zaini," and ran Disk Utility to repair disk permissions. The only difference was, I ran it from Recovery Mode by restarting and holding down command+R. (In Recovery Mode or "Recovery HD," you're actually booting from a partition on your hard drive, while your Startup volume is unmounted.) I really didn't see how repairing permissions on my Startup drive would work, since the jpegs in question were on a different drive…but it worked for me. I like it when the first solution tried is the one that works!
