Thanks for responding. I have ipad first generation. When i open photo app it goes to photo screen and shows all my photos in thumbnail view. At the top of screen I only have three choices, photos, albums, events. switching from photos to albums shows album titled last import and a album titled All Imports. Opening either shows all the same photos as in the opening screen.
I took some pictures on my camera and imported them thru the camere connection kit. Still same result. When I open photo app it goes to photo screen and show orginal photos + the new photos in thumbnail view only. My new ipod with ios 5 pre installed show a camera roll.
Seems like upgrading may have left out some files???
I've tried resetting, looking in iexplorer, etc.
