when you share photos via mail the titles under the photos do not appear . WHY. they used to in iphoto

That feature was left out of Photos. Tell Apple what missing features you'd like restored or new features added in Photos via https://www.apple.com/feedback/photos.html.

iPhoto was not deleted from your hard drive, only removed from the Dock. If you have iPhoto 9.6.1 you can still use your iPhoto library.

If you don't have that version but some earlier version of 9.x try following Terence Devlin's instructions in this post to obtain iPhoto 9.6.1 from the App Store:

Go to the App Store and check out the Purchases List. If iPhoto is there then it will be v9.6.1

If it is there, then drag your existing iPhoto app (not the library, just the app) to the trash.

Install the App from the App Store.

Sometimes iPhoto is not visible on the Purchases List. it may be hidden. See this article for details on how to unhide it.

One question often asked: Will I lose my Photos if I reinstall?

iPhoto the application and the iPhoto Library are two different parts of the iPhoto programme. So, reinstalling the app should not affect the Library. BUT you should always have a back up before doing this kind of work. Always.

No they will not be in iPhoto. You need to export them from Photos to the Finder and then import them to iPhoto.
