I simply want to put the photos onto the iPad to show them to my friends & relatives. They are on a Windows 7 PC and a memory stick. They are no longer on a camera card. You say "plug the [Pad in", but do you mean to the PC or only to an Apple computer? Do I simply have to download the PhotoSync app onto the iPad, or also onto the computer? My wife has a Mac Book Pro, so would it be easier to put the photos onto that, and then onto the iPad through iTunes?
Thanks for all your help.
Best solution, in my opinion, given what you said you want to do.
If the iPad is on iOS 7.x, the Mac is running OS X Mavericks (10.9.xx), and you have the latest version of iPhoto; you can sync Shared Photo Stream albums using iCloud.
You would import the photos into iPhoto from the USB stick, select them, and choose the iCloud option from the share menu, then either select or create an album.
On the iPad you go to Settings > Photos and turn on Shared Photo Streams.
The photos will show up in the Photos app under the Shared tab. You generally have to open the new album before the photos will sync from iCloud, but once synced they are stored locally; available all the time.
Shared Photo Streams are designed to be shared between your devices and/or with others. The others is optional, so they can be private if you like.
If you do not already sync your iPad to a computer using iTunes, I don't really recommend you start, not just to get an album onto the iPad. iTunes will want to sync everything, and unless you get the initial settings right it will make changes. Hold in mind you're highly unlikely to lose anything permanently, but it could cost you hours, or even days to get thing back to where you started.
Instead, consider a third party app like
Photo Manager Pro. It has several options for importing photos, and you can manage your albums independent of iTunes or the Photos app (though you can still copy photos back and forth between Photo Manager Pro and Photos). I do not use Photo Manger Pro myself, preferring the iCloud solution, but the app has been recommended by many forum members.
The PhotoSync app I mentioned earlier is for when you want photos to end up in the camera roll, a kind of general storage place for photos. You can use it, and then use the Photos app to move/copy photos to Shared Photo Stream albums on the iPad; but it would be tedious compared to the other methods. And you have to delete the photos out of the camera roll later to avoid duplication.
I do create and populate Shared PhotoStream albums on the iPad, but this works best when you are starting a collection and only adding a few at a time, especially if the photos were taken on the iOS device.
