How to write newest img with PHP?

I have a camera that save img every 60 sec and upload to my FTP server.
I would like to upload this img to my website.
The problem is the folder change every day and the img name change every time.
Have any PHP code that find the last uploaded file?
the img location is: camera/"year,month,day"/images/"img file"
