Please can you help me find my google photo's that where backed up?

[AC Question]

I downloaded google photo's on to my Sony Xperia then Synced the photo's from my phone to the google app. Once it showed back up complete i deleted the photo's on my phone to make more space but when i went in to the app non of the photo's showed.. It shows the newer ones but not those. I tried to look in google drive and picasa but still non of those photo's are showing.
