How do I retreive photos after deleting in the trash

Ok

I did copy my Iphoto to external drive ( twice on 2 different drives )
just to make sure
then I deleted all pictures on iphoto on the mac
when I try and open them on the saved copy they are not there
it is like the 2 back up copies have automaticly synced

HOW can I get them all back ?????

How are you trying to open them?
They will not be in iPhoto until you import them back.

Pics back

Hi
Where are they ?
I thought that they would be in the saved copy on the external - but NO - all gone
so where are they now ?
and how do I import them back ?

If you emptied the Trash in iPhoto, or closed the application, not good news I am afraid. Have a look in Trash in iPhoto and make sure they are not still stored there. This has been discussed in Apple Discussions:-

Any chance you have backed up to an external using cloning software?
