Refresh thumbnail photos app in ipad

Quit the photos app completely and then restart the iPad and see if that works.

Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold downicons he photos app icon until it begins to wiggle. Tap the minus ➖ sign in the upper left corner to close the apps. Restart the iPad.

Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

See if this helps.

Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

What album are these photos located in? Are they in the Camera Roll - photos that you took with the iPad - or are they photos that you synced from iTunes?

I'm sorry but if you are using Photo Stream I am totally clueless. I don't use photo stream at all. See if one of these support sites offers any information that might help you.

That might be the case. Actually, if the error is in the album - the last 12 months album - isn't that an album in iPhoto? That would mean that it was an album that you synced to the iPad from the Mac.

But did you try syncing with the MacBook again?
