How to get iPhoto on a mac computer????

Photos has far better editing capability than iPhoto. You just need to experiment with the various editing modes to see how each works. For example for the Adjust mode click on the blue Add button to add all of the adjust modes to the vertical menu.

I loved iphoto! The new Photo doesn't have the user-friendly adjustments (easy adjustments for color, and tilted photos, to start with) that iPhoto had, and the layout is just not as good. I sincerely hope they bring back iPhoto.

So I got this item with the CD, but after 6-7 years the disc is lost. Is there a way to redeem it this through the great web?

Do perhaps have iPhoto still on a backup - as part of an older Time Machine backup, for example? If you ever updated iPhoto iPhoto 9.5.1 or newer, you may be able to reinstall iPhoto from the AppStore, from your purchases history on the fourth tab of the AppStore. But if you never updated to an AppStore version, use the successor "Photos" to open your iPhoto Libraries and to get access to your photos.

If your computer shipped with 10.6.8 or earlier, or you got it on an iLife DVD, reinstall it from a disk.

If your computer shipped with 10.7 or newer or you got it from the Mac App Store, log into the Mac App Store with the same Apple ID, click on the Purchases tab, and redownload it from there.

If the computer’s running Mac OS X 10.10.3 or newer, you can instead use Photos.

Yes - iPhoto is a dead product and will quit working someday with out warning during some upgrade - Photos is a new and different program with different work flows but in nearly every way better once you learn it - learning Photos is your best approach

My iPhoto stopped working so I deleted the app. But then i found out that I wasn't able to reinstall it.

In what way did iPhoto stop working? Has the iPhoto icon been crossed out to indicate, that your current iPhoto version has not been compatible with El Capitan? Only iPhoto 9.6.1 can run on El Capitan. If your iPhoto version stopped working, because it was to old and has not been compatible, migrating your iPhoto lIbrary to Photos will be the best option. See: Updating from iPhoto to Photos for OS X - Apple Support

But if iPhoto has been working on El Capitan and suddenly stopped working with crashes or similar, your iPhoto library may have problems and it would be good to find out, why iPhoto stopped working, before you try to migrate the library to Photos. Then it would be better to repair or rebuild the iPhoto Library in iPhoto before you migrate it to Photos. Have you tried to restore the iPhoto application from the last Time Machine backup you made before you deleted iPhoto?
