I accidentally deleted a picture on my iphone 4s… How do i get it back or undo it?

No way to unless it was saved or backed up on your P. C

Unless you had previously backed up your pics u mostly likely can't

If you have backed up before you deleted the picture, just restore from iTunes backup files with iTunes.
1.Configure iTunes so that it does not automatically sync with your iPhone when your phone is connected to your computer
2.Connect your iPhone to the computer.
3.Open iTunes
4.Right-click on your device and press 'Restore from backup…'
By the time the restore is done. Note: If your other files like new contacts, new messages that have not backed up would be rewritten.

If this didn't work for you, you may try professional data recovery tool to recover them. Actually no matter the data lost has been backed up or not, they are marked as "deleted" by the device's internal database when deleted but still stored in the database. Good luck!
