Accidently deleting photos from iPhone when synced into PC?

Last night I seriously messed up and deleted two important photos from my iPhone 5s while it was plugged into my PC. I opened up the DCIM folder and in 103APPLE, I permanently chose to delete them mistaking the pictures for others. I couldn't find them in my iCloud. Please is there any method to recovering them? If so, would the lost files be on the computer or phone?

At this point a key word such as "Permanently" usually means that. There's a chance you could check your computers "Trash" to see if it is there. From my knowledgte the iCloud is synced with your phone in a current state setting. Don't believe there's a restore feature on the Cloud either. So you may have lost them forever.
