Q: When the iPhoto for iPhone and iPad will be supporting the ios8?

iPhoto has been discontinued, sorry.

You are supposed to migrate your iPhoto Library to the "Photos" app, see this help document:   Migrating from iPhoto for iOS to Photos on iOS 8

Not all can be migrated - no Journals, no books, and you will not be able to add new tags and captions.

See this on how to browse your photos in the Photos.app:  Get help finding your Photos in iOS 8

You may want to send feedback to Apple about the features you are missing: Apple - iPhoto - Feedback

So, all of us who paid for iPhoto are now out of luck. That Is absolutely terrible*****! I haven't even had that app for a year, maybe not even six months, and loved it. All that was good about it had better be in Photos, but I bet it won't be. Dark background for starters..........

***** represents what one does with a straw, but is too strong for this forum, so I changed it to " is absolutely terrible. "

iPhoto needs iOS 7.  The problem is, that there is no Apple supported way back to iOS 7, once we have upgraded to iOS 8.

The photos.app is right now a poor substitute for iPhoto; I hope it will be updated soon to support the missing features - tag, titles, info panels, and most important brushed adjustments and retouching.

Tell Apple which iPhoto features you'd like to see incorporated into the Photos apps via http://www.apple.com/feedback/iphone.html and Apple via http://www.apple.com/feedback/icloud.html.

Thanks, Old Toad! I have sent feedback to Apple, albeit on the iPhone section (I have an iPad mini) and will send another to the iCloud link you provided. I only paid for the app because I hated the "upgrade" to Photos, so I feel as if I wasted my hard-earned money. Had I known this was coming, I wouldn't have bothered! I liked iPhoto a lot......
