iphoto chronological order

how to I get each and Every Pic in iphoto in order?
It shows 'Events" in order but the pics over lap each other.
Seems to be in order by when I physically down loaded each time (before there was icloud)........

I tried...."view"
"sort photos"
"by date"

It still does NOT put each and every individual photo in order......

I don't understand what you mean by this: "It shows 'Events" in order but the pics over lap each other."

On my machine, Events shows the pictures in chronological order.

In the Photos view I can sort photos by date, and this shows them in chronological order *PROVIDED* they were shot with a digital camera (which embeds the time/date etc info into the picture, which iPhoto uses for sorting). Photos that came from a scanner or in some other way don't have the correct date/time on them must be manually corrected to the proper date/time within iPhoto, then they "magically" move to the correct order.
