Format your memory card without data backups on clouds or other online storage?
Stop adding anything new to this formatted memory card and also connect it to computer to see whether your lost pictures are still recoverable.
Simply download formatted memory card data recovery software to the same computer and run it to scan this formatted memory card and retrieve all scanned card files back, like:

And then, save everything restored on another drive or card in case of any data recovery failures.
From now on, prepare card data backups all the time.

OK! I hope you can learn a lesson to back up all your important data well in the future after experiencing this trouble.
But, now, what you should do is really simple:
Firstly, stop using this formatted memory card immediately in case that anything new will rewrite your wanted photos.
Secondly, plunge this memory card to your computer and prepare to retrieve all your deleted photos.
Thirdly, apply a deleted photo recovery freeware to retrieve all your deleted photos back successfully:

I believe this data recovery can work perfectly on your memory card just in the same way as it completely retrieves all the deleted data of my friend off from his camera memory card. Just give it a shot!
Fourthly, save and back up all the restored photos on a different card or drive in case of data recovery failure.
Note: Never forget to back up everything important at least on two cards or locations in the future.
Good luck!

It is possible to recover formatted memory card only when you don't save any data to the formatted memory card. Because when you format memory card, the data remains there but the space it occupies is made available. So after the first format, you'll be able to carry out formatted memory card recovery with a near 100% success. But once new data is written to memory card, the chance of full memory card recovery will become less.

1) Install Tuneup utilities 2008 in your computer (OS MS Windows XP)
2) Connect memory card (using memory stick)
3) Working Tuneup undelete program.
4) Restore accidentally deleted file in memory card.
