The forum is advising you you can link your log-in here to a Microsoft or Google account. You don't have to. You just need a valid email address to join this forum and get the privilege of a reply button in threads (plus oh, so much more goodness).
Continuing to make new threads is not going to help you... It scatters the advice and now you have to track multiple threads.
If you don't want to register here, that is fine also. Please be advised, however, to get the best help certain questions might have to be answered. That means you do have to register to reply to a thread. You may want to keep making new threads to "answer" the old thread... But we are volunteering here and not many will want to track all your threads to keep up to date with your progress. Remember: this is a fan based News and Discussion site. It is not run by Microsoft, Lumia or any entity responsible for the manufacture, instruction or warranty related to your phone.
I didn't answer the first thread because you have not put in enough information.
Let me make a couple of assumptions and guesses anyway to try and help you out and keep you from creating more threads to get lost here in this overcrowded space. Also, by keeping all the info in one thread it may help someone else with the same problem who may read this later...
If the information you deleted was on your phone... You probably will not get it back via a desktop data recovery program. It's Windows Phone, separate from Windows and the software may corrupt vital files.
If the information was on a microSD: unmount the card via Storage Sense, power down the phone and remove the card. Put the microSD card in an adapter and plug it into a card reader attached to your PC. Make a folder and copy over all the files on the card for safekeeping. Run the data recovery software you got and point it at the card reader as the drive to recover. Follow the documentation for that program. I never used that one. Read about how it works and follow the instructions. If it screws up your microSD card that is way better than having it screw up your phone...
If you can recover the files, great. Copy them to your computer. Format your memory card for a fresh start (FAT32 format) and then copy over anything you want back on there.
Set your phone to always upload your pics to OneDrive from now on. It is free and easy. It will only upload them over WiFi so it won't eat up your cellular data.
Your other alternative is to not mess with it yourself and hire a data forensics firm to try and recover the data. That is an expensive option. Depending on how vital the pictures are to you it may or may not be worth the expense.
