i use iPhoto for my pictures. have been for years.
why ois it not a free app and that photo app is the only
iMac, OS X Yosemite (10.10.3)
You need to explain
iPhoto is not a free app and never has been - it comes with every new Mac - updates are free - upgrades may be charged for
We have no idea what you are trying to do or what problem you have run into until you provide details including the version iPhoto that ti have and what has changed recently

Why do you think iPhoto is not free?
What happened? Did you just upgrade to Yosemite and iPhoto is gone from the Dock?
Look into your Applications folder. Is iPhoto there? Then drag it back to the Dock and try to launch it.
If the iPhoto icon is crossed out, you need to update to iPhoto 9.6.1. Only that version is fully compatible with MacOS X 10.10.3.
Apple stopped selling iPhoto, but anyone who bought iPhoto from the AppStore or updated it to a version sold at the App Store (iPhoto 9.4.5 or later) will be able to reinstall from the App Store by downloading from the Purchases tab.
If you have any version of iPhoto, that has been updated from the AppStore and is associated with your Apple ID, try to reinstall from the "Purchases" page.
The step "Trash the incompatible iPhoto version, but don't empty the Trash." must not be skipped. If Spotlight sees a version of iPhoto installed, the AppStore will try to update instead of reinstall, which does not work.
why do i have to pay to continue iPhoto
